Product Description
The ZH-44062W is a 6-channel current data acquisition module designed for multi-channel DC current monitoring in industrial and automation applications.
The module supports six independent current acquisition channels and uses external current sensors for flexible installation and measurement. Depending on the selected configuration, the system can support DC current measurement or AC/DC universal true RMS measurement.
With high-precision AD conversion, isolated measurement channels, closed-loop Hall-effect current sensors, fast dynamic response and up to 0–1000 Hz frequency response for AC/DC universal models, the ZH-44062W is suitable for demanding industrial current monitoring applications.
The module supports RS485 or Ethernet communication with standard Modbus RTU or Modbus TCP, allowing direct integration with PLCs, SCADA systems, industrial PCs and other automation systems.
External sensors also provide greater flexibility for current measurement ranges, with available sensor configurations from 5A to 200A AC/DC depending on the selected sensor.
