DIGITAL AND ANALOG I/O MODBUS DEVICE

The RMS1-RM is an industrial I/O expansion module designed for easy integration with any control or automation system operating through the Modbus Serial RTU/ASCII protocol.

Additionally, it can function as a pulse counter on its digital inputs and also allows the creation of an I/O “TUNNEL”, for both digital and analog signals, using master mode.




  • 4 digital inputs (standard inputs and pulse counters)
  • 2 digital outputs
  • Up to 4 analog inputs (0-10V and 4-20mA)
  • Up to 2 analog outputs (0-10V and 4-20mA)
  • Power supply of 10 to 30Vdc
  • RS232/RS485 Serial Port
  • USB port configuration
  • Modbus RTU/ASCII slave
  • Master mode to create I/O tunnel
  • Dimensions: 70 x 90 x 65 mm (HxWxD).
