The CAN-Logger100 CR records traffic from a CAN 2.0A/2.0B network on a single isolated CAN port, so engineers can capture bus activity without a PC attached for the whole session. Each message is time-stamped at 10 us resolution and written to an SD or SDHC card in binary format, ready for offline analysis.Logging runs continuously and the device is configured through a supplied utility tool over its USB 2.0 High Speed port. The utility can also transmit and receive CAN messages, which helps when checking node behaviour during commissioning or fault finding. The CAN side offers a DIP-switch selectable 120 Ω terminal resistor, a programmable baud rate from 10 kbps to 1 Mbps and acceptance filter configuration.The housing is metal and wall mountable, with an operating range of -25 ~ +75 °C. It can be powered from USB or from a +10 VDC to +30 VDC supply, which suits both bench use and fixed installations on a CAN network.ApplicationsCAN bus data collection and processingCAN network analysis and diagnosticsRecording CAN message traffic for later review

CAN-Logger200 CR is a two-port CAN bus data logger for capturing traffic on CAN networks without a PC attached for the whole session. Each CAN message is time-stamped at 10 us resolution and written to an SD or SDHC card, so recorded data can be reviewed later for analysis and fault diagnosis.Logging runs continuously and stores binary files on a card, 4 GB by default and up to 32 GB supported. When the card is full, the logger overwrites older data. A bundled configuration utility sets the CAN acceptance filters and baud rate from 10 kbps to 1 Mbps, and can also transmit and receive CAN messages over the USB 2.0 Type B port.The CAN side is isolated, with 2500 Vrms photocoupler isolation and 3000 VDC DC-to-DC isolation on the CAN port. Each M12 5-pin CAN connector has a DIP-switch selectable 120 Ω terminal resistor. The unit runs from +10 VDC to +30 VDC or from USB power, and its metal housing is designed for wall mounting.ApplicationsCAN bus network data collection and analysisCAN bus diagnostics and troubleshootingRecording CAN traffic for later reviewMonitoring and control of CAN-based industrial systems

ECAN-240 CR is a Modbus TCP to 2-port CAN bus gateway. It connects two CAN bus networks to an Ethernet network, so CAN devices can be reached from Modbus TCP clients and the two CAN segments can exchange data through the module.Each of the two CAN interfaces follows ISO 11898-2 and supports CAN 2.0A and CAN 2.0B frames, with baud rates from 10 k to 1M bps set by rotary switches. A built-in 120 ohm terminal resistor is enabled or disabled with a DIP switch. The CAN ports are isolated, rated at 3000 VDC for DC-to-DC and 2500 Vrms for the photo-coupler stage.Beyond Modbus TCP server operation, the gateway offers pair connection between CAN networks over TCP or UDP, and a transparent mode in which TCP (port 10003) or UDP (port 57540) packets carry CAN frames for custom software. The metal housing is rated for -25 ~ +75 °C operation and mounts on a DIN rail.ApplicationsIntegrating CAN devices into Modbus TCP industrial networksLinking two CAN bus segments across Ethernet via pair connectionCustom TCP or UDP applications that access CAN frames directly

The ECAN-240-FD bridges CAN and CAN FD networks to Ethernet using the Modbus TCP industrial protocol. It gives an Ethernet-based controller or SCADA system access to two CAN bus networks through a single RJ-45 port, so CAN devices can be integrated into a wider industrial network without custom gateway software.The module provides two CAN bus interfaces, each on a 9-pin D-sub connector, and supports CAN 2.0 A/B and CAN FD in line with ISO 11898-2. CAN FD can be switched between the ISO and non-ISO (Bosch) standards, and a built-in DIP switch enables or disables the 120 Ω terminal resistor on each bus.Beyond Modbus TCP server operation, the gateway can also run in TCP/UDP transparent mode for CAN and CAN FD frames, or in CAN pair mode, which links two CAN networks across Ethernet over UDP. The ordering code ECAN-240-FD CR is the RoHS-listed version of this model.ApplicationsModbus TCP access to CAN and CAN FD devicesTCP/UDP transparent communication between CAN devices and Ethernet clientsCAN pair connection linking two CAN networks over Ethernet via UDP

The I-2533 CR is an intelligent CAN bridge that connects two CAN bus systems over a multi-mode fiber optic link. It converts CAN bus signals to optical signals, reshapes them at the far end and supports both CAN 2.0A and CAN 2.0B, fully compatible with ISO 11898-2.Compared with the I-2532, this model adds CAN baud rate and message filter configuration. This is useful when joining two networks that run at different baud rates. Because the baud rate does not limit the transmission distance, the total network length can be extended, with up to 2 km per fiber link at any CAN baud rate.The bridge accepts a user-defined baud rate within the 10 k ~ 1 M bps range and includes a software utility for message filter setup. Its 512-record CAN Tx and Rx buffers and broken line detection for the fiber cable help keep data flowing reliably across the link.ApplicationsEV charging station managementControl and monitoring of CAN-based systems across various industries

I-2533-UTA CR is a CAN bridge for extending a CAN bus across fibre optic cable. It converts CAN signals to optical signals at one end and reshapes them at the other, so two CAN segments can be joined over a single ST multi-mode link with a reach of up to 2 km.The bridge suits networks where the two sides run at different baud rates. Its baud rate and message filter settings can be configured, and because the fibre link does not depend on the CAN baud rate, the distance limit of the CAN bus is not reduced. The total network length can therefore be extended while the segments keep their own timing.Its CAN side supports both CAN 2.0A and CAN 2.0B under ISO 11898-2, and it is rated for an operating range of -40 to 75 °C. Mounting is on DIN-rail, and a broken fibre cable is detected.ApplicationsLinking two CAN bus networks over fibre optic cableJoining CAN segments that run at different baud ratesExtending total CAN network length beyond the bus distance limitEV charging station managementControl and monitoring across various industries

I-2533CS CR is a local CAN bridge that carries CAN bus signals over single-mode fibre, allowing two CAN networks to be joined across distances that copper cabling cannot cover. The link reaches up to 30 km at any CAN baud rate, so the reach of each bus segment is not reduced when the networks run at different speeds.Each CAN network is isolated from the other, so a bus error on one side does not disrupt operation on the other. Both sides can run at different baud rates, and the bridge also supports user-defined baud rates. Fibre broken line detection and a utility tool for CAN message filter configuration help with commissioning and fault finding.The unit mounts on DIN-rail and uses a removable terminal block for easy installation in control cabinets.ApplicationsRemotely Operated Underwater Vehicle (ROV) systemsExtending CAN bus networks over long fibre runs

The I-2533CS-60 extends a CAN bus over single-mode fibre. It converts the electrical CAN signal to a 1310 nm optical link on an SC connector, so two CAN networks can be joined over up to 60 km. Because the link is independent of the CAN baud rate, the distance is not reduced when a faster rate is used, and a fault on one CAN network does not stop the other from operating.Each unit uses an NXP TJA1042 transceiver and supports CAN 2.0A and CAN 2.0B to ISO 11898-2. The baud rate is set with a rotary switch or can be user-defined, and a built-in switch enables the 120 Ω terminal resistor.

The I-2533CS-A is a local CAN bridge that links a CAN bus segment to a single-mode fibre link, so two CAN networks can be connected over long distances. It converts the electrical CAN signal to optical transmission, and Wavelength Division Multiplexing (WDM) lets bidirectional CAN traffic run over one fibre core, reducing the cost of cabling.The bridge is supplied as one half of a matched pair and must be used with the I-2533CS-B at the far end. The maximum transmission distance of 15 km is stated to apply at any CAN baud rate, and the two networks can run at different baud rates. A bus error on one network does not affect the other, which helps keep faults contained.The CAN side is electrically isolated at 2500 Vrms and supports CAN 2.0A and CAN 2.0B to ISO 11898-2. Configuration is handled by a rotary switch for standard baud rates, a user-defined baud rate option, a built-in 120 Ω terminating resistor switch and a utility tool for CAN message filtering over RS-232.ApplicationsExtending CAN bus networks over long single-mode fibre runsConnecting two CAN networks that operate at different baud ratesElectrically isolating CAN segments in industrial control and monitoring systems

The I-2533CS-B is a local CAN bridge that connects a CAN bus segment to a single-mode fibre link, allowing two CAN networks to communicate across distances of up to 15 km. Wavelength division multiplexing carries bidirectional CAN data over a single SC fibre, which reduces the amount of fibre cable needed for the installation.The I-2533CS-B must be used together with the I-2533CS-A, as the two units are a matched pair due to hardware limitations, so both must be purchased. The link distance does not depend on the CAN baud rate, and the two networks can run at different baud rates. A bus error on one CAN network does not affect the other, and the fibre link includes broken line detection.Configuration is handled by a rotary switch for standard baud rates or a user-defined rate between 10 k and 1 M bps, an on-board switch for the 120 Ω terminal resistor, and a utility tool for CAN message filter setup through the RS-232 utility port.

The I-2533CS-FD bridges two CAN or CAN FD networks over single-mode fibre. It converts the electrical CAN/CAN FD signal to optical transmission, so the physical length of a CAN segment is no longer limited by copper cabling. It is a practical choice where a CAN bus must span a site, a building or a distance beyond the reach of standard bus wiring.Each network runs at its own bit rate, so the two sides can operate with different CAN or CAN FD baud rates. A bus error on one network does not disrupt the other, which helps keep faults contained. Basic CAN message routing is available through Group ID settings, and message filtering can be configured on the CAN side.The unit mounts on a DIN-rail and is powered from +10 VDC to +30 VDC. Status LEDs show power, CAN activity and fibre status, and fibre broken-line detection is included. Firmware can be updated over USB.ApplicationsLinking two CAN or CAN FD bus networks over long single-mode fibre runsExtending CAN bus segments beyond the distance limits of electrical cablingIsolating bus faults between separate CAN networksConnecting CAN networks that operate at different bit rates

The I-2533T-FD is a local bridge that connects two CAN or CAN FD bus systems over a multi-mode fibre optic link. It converts the electrical CAN/CAN FD signal to optical transmission, so the two networks can be separated by a distance that a copper bus cannot cover.Because each network is isolated from the other, the baud rate on one side does not limit the transmission distance on the other, and the two networks can use different CAN or CAN FD baud rates. A bus error on one network does not affect the operation of the second network, which helps keep faults contained.Setup is handled by a DIP switch for CAN/CAN FD baud rate, a switchable 120 ohm terminal resistor, CAN bus message filter configuration and basic message routing through Group ID settings. Fibre broken line detection is included for monitoring the optical link.ApplicationsConnecting two separate CAN or CAN FD bus systems over fibreExtending the total working distance of a CAN bus installationControl and monitoring networks across varied industrial installations

The I-2534 CR is a 4-port CAN bus switch with four independent channels, suited to building star or tree CAN topologies. Each channel handles CAN 2.0A and CAN 2.0B frames and conforms to ISO 11898-2, so it can join existing CAN segments without changing the node hardware.Engineers typically use it to divide a large network into several subnets, which increases the number of nodes a CAN network can support, or to extend the physical reach of a bus. It can also pass data between segments running at different baud rates. Baud rate is set with a rotary switch, the 120Ω terminating resistor is selected by DIP switch, and CAN filters and CAN-ID mapping can be configured with the supplied utility tool.The unit has a flame-resistant plastic casing for DIN-rail mounting and accepts a +10 VDC to +30 VDC supply.

The I-5534-M (ordering code I-5534-M CR) gives engineers four independent CAN channels that can be arranged in star or tree topologies. Use it to divide a large bus into several subnets, which raises the practical node count of a network, or to extend the cable run of an existing CAN system.Each channel can run at its own baud rate, selected with a rotary switch from 5 kbps to 1 Mbps, so segments with different speeds can exchange data through the unit.

Modbus RTU to CAN Converter.

The I-7530A-MR-G is a Modbus RTU to CAN converter for control systems that have a serial Modbus RTU master but no CAN interface. It bridges the two networks so that standard Modbus function codes can access CAN devices, which is useful when sensors or actuators are only available with CAN connectivity.In Modbus Slave mode, the converter answers function codes 0x03, 0x04, 0x06 and 0x10 to read or write CAN messages. Its firmware also reserves dedicated memory for up to 100 kinds of urgent CAN messages that must be handled immediately, alongside the normal receive buffer. Modbus Master mode, which lets the converter poll several Modbus RTU slaves and relay data to CAN devices, requires firmware v1.11 or later.Besides Modbus, the unit can convert CAN messages to and from ASCII command strings, or work in pair-connection mode to pass data transparently between two RS-232, RS-422 or RS-485 devices over CAN bus. The serial ports cannot be used at the same time.

The I-7531-FD-G CR is an isolated repeater for CAN 2.0A/B and CAN FD networks, with two CAN ports that link two bus segments running at the same baud rate. Signals weakened by long cable runs or electrical noise are reshaped and retransmitted on the second port, which helps keep a marginal bus stable.The module detects the CAN bus baud rate automatically, so no parameters need to be set. Once wired to the bus and powered from +10 VDC to +30 VDC, it is ready to operate. A built-in 120 Ω terminal resistor can be selected by jumper. Digital isolation is rated at 2500 Vrms and the DC-DC section at 3000 V.Note that the repeater adds a typical physical-layer delay of 175 ns and does not extend the maximum communication distance of the bus. Where the reach of the CAN segment itself must be increased, the manufacturer points to the I-7532M-FD instead.ApplicationsExtending the usable length of CAN bus segments affected by cable attenuationReducing the effect of electrical noise on CAN networks by isolating two segmentsJoining two CAN segments that run at the same baud rateIndustrial control cabinets using DIN-rail mounted CAN infrastructure

I-7531-FD-UTA-G is a two-port isolated repeater for CAN 2.0A/B and CAN FD networks. It links two CAN segments that run at the same baud rate while keeping them electrically isolated, which helps where ground potential differences or noise would otherwise disturb the bus.If a signal arrives at one port weakened by cable length or interference, the module reshapes it and retransmits it on the other port. It detects the bus baud rate automatically, so no parameters need to be set: connect the bus, apply power and the module operates. Compared with the I-7531-FD-G, this variant is rated for a wider operating temperature range.Note that the repeater adds a small physical-layer delay (typically 175 ns) and does not extend the maximum communication distance of the CAN bus.ApplicationsIsolating and bridging two CAN bus segments with the same baud rateRestoring signal quality on long CAN cable runs or in electrically noisy environmentsCAN FD networks in industrial installations operating across a wide temperature range
