Modbus interface for analog input

The DigiRail product range allows to interface with a Modbus RTU communication system analog inputs, counting logic inputs or NO/NC relays depending on the model chosen. It is an easy and practical way to allow the implementation of a supervision system. The input signals are isolated from the power supply, which greatly increases the protection of other systems and significantly reduces unwanted interference and sensor instabilities. The DigiRail can be configured and calibrated via the RS485 interface with the Digiconfig software for Windows. It automatically detects all active devices on the bus and accesses them using Modbus RTU commands.
