Metz ModBus MR-SI4 S0/Pulse Input Module

SKU: Metz ModBus MR-SI4 SO/Pulse


The Modbus MR-SI4 S0 module with 4 S0 or pulse inputs was developed for decentralized switching tasks. It is suitable for counting S0 counter pulses. This allows very good integration of the module into an energy controlling system. In case of a power failure, the last counter readings are saved. The MR-SI4 S0 inputs can be scanned by means of standard registers via a Modbus master. Module address, bit rate and parity are set with two rotary switches on the front or by software. Suitable for decentralized mounting on DIN TH35 rail in electrical distribution cabinets.Connection with screw type terminal blocks.  It is also available with BACnet MSTP and can be integrated via  IQnexus IoT Platform into Building Automation, Energy-Management and SCADA.


  • Mounting on a 35 mm DIN rail
  • Simple integration into the LVD Board
  • RS485 ModBus RTU Slave
  • Easy to configure
  • IQnexus IoT platform for LoRaWAN
