The DigiRail-2R is a DIN rail mounted Modbus I/O module with two digital relay outputs activated by serial interface RS485.

Both outputs are electrically isolated from the serial interface and the module supply and there is no electrical insulation between serial interface and supply. Configuration of the DigiRail-2R is performed through the RS485 interface by using Modbus RTU commands. The DigiConfig software allows the configuration of all features of the DigiRail as well as its diagnostics.
