Produktinformation "DNM-831I-100V-500A Voltage Attenuator and Current Transformer Module"
The DNM-831I-100V-500A conditions one high voltage and one high current signal into a level that standard analog input modules can read. The voltage path attenuates up to ±100 V to ±10 V, while the current path uses a clip-on current transformer rated for ±500 A, also scaled to ±10 V.
Key points for system design:
- Isolation of 3000 VDC between the modules and 3000 VDC between channels keeps noise from passing from inputs to outputs or between channels.
- Metal casing and DIN-rail mounting suit control cabinet installation.
- Operating range of -25 ~ +75 °C with a 10 ~ 90% RH non-condensing humidity limit.
This ordering code includes the CA-040415 cable and the ASO-0001 current transformer. The clip-type transformer has an inside diameter of Φ21 mm and a 1.5 m leading cable, so it can be fitted around a conductor without disconnecting it.
Applications
- Measuring high AC or DC voltage up to ±100 V with standard analog input modules
- Measuring high current up to ±500 A without direct contact with the conductor
- Feeding high-level voltage and current signals into I-7017, I-87017, M-7017RMS or I-87017W-RMS modules
