  • Color: gray
  • Feature 1: 4x IN (U or I) active
  • EAN-No: 4250184165699

The Modbus module with 4 analog inputs was developed for decentralized switching tasks. It is suitable for detecting currents and voltages of, for example, active temperature sensors, electrical vent and mixing valves, valve positions, etc. Each input can be set as current or voltage input by DIP switches on the front.The inputs can be scanned with standard registers via a Modbus master. The module address, the baud rate and the parity are set with two rotary switches on the front or by software.Suitable for decentralized mounting on TH35 rails according to IEC 60715 in electrical distribution cabinets.
