Novus Automation DigiRail-2A 
Full manuals and communications information provided.

The universal analog input Modbus module DigiRail-2A is a remote measuring unit with two configurable analog inputs. An RS485 serial interface allows reading and configuring these inputs through the communication network. It is appropriate for mounting on DIN 35mm rails. The inputs are electrically insulated from the serial interface and the module supply. DigiRail-2A configuration is performed through the RS485 interface by using Modbus RTU commands. The DigiConfig software allows configuring all DigiRail features as well as performing its diagnostic. DigiConfig offers features for detecting the devices present in the Modbus network and for configuring the DigiRail-2A communication parameters.
