MR-DI-4 Lo 4-input digital module, Modbus RTU

Why choose the MR-DI-4 Lo?

The MR-DI-4 Lo expands the system with four digital inputs designed to read low-voltage signals and makes their status available via Modbus RTU.

What does this mean in practice?

  • The module has 4 independent digital inputs.
  • The input signal voltage range is 6–30 V AC/DC.
  • It is possible to configure the active state of the input and the triggering method.
  • The input time filter allows you to specify the conditions for responding to a signal change.
  • Input states and configuration parameters are accessible via RS-485 Modbus RTU.

MB Config
