Produktinformation "DNM-831I-100V-1000A Voltage Attenuator and Current Transformer, 1-ch Metal"
The DNM-831I-100V-1000A pairs one high-voltage attenuator channel with one high-current transformer channel, letting a standard analogue input module measure large AC or DC voltages and currents. Inputs up to ±100 V and ±1000 A are scaled to a ±10 V output.
Electrical isolation is rated at 3000 VDC between the module's internal sections and between channels, which helps keep input-side noise away from the outputs. Its high input impedance and linear attenuation ratio make it suitable for measurement chains where signal integrity matters.
This ordering code includes the CA-040415-1 cable and ASO-0024 current transformer. The clip-type transformer, with a 40.5 mm inside diameter, fits around a conductor without disconnecting it. The metal housing mounts on DIN-rail and is rated for -25 ~ +75 °C operation.
Applications
- High-current measurement using a current transformer and analogue input module
- High-voltage AC/DC measurement with isolated voltage attenuation
- Connection to analogue input modules such as I-7017, I-87017, M-7017RMS and I-87017W-RMS
