The DigiRail-2A is a DIN rail mounted Modbus IO interface, with 2 input channels designed to accept two standard analogue inputs and connect to serial Modbus-RTU networks on standard 2-wire RS485.
Both inputs are electrically isolated from the serial interface and the module supply to avoid interference. The DigiRail-2A can be configured using the free DigiConfig software, ideally using the USB-i485 comms converter. The DigiConfig software also features device detection, automatically detecting all DigiRail devices on the modbus network allowing quick and easy configuration.
