WBIO-AI-DCM-4 I/O Module
This is the approved revision of this page, as well as being the most recent.
Module is discontinued and replaced by WBIO-AI-DV-12 module
Purpose
The device is designed for tasks that require monitoring of currents and voltages in DC networks, for example for technical metering of electricity.
The device directly measures the voltage and current in the load. The values obtained are used to calculate power (kW) and energy (kWh).
Technical specifications
Contains 4 inputs for Hall sensors for load current measurement and 1 (2) input for voltage measurement.
