The Novus DigiRail series of Modbus RTU IO modules are rugged, isolated DIN rail mount units for SCADA or PLC systems. The DigiRail-2A features 2 universal analog inputs that accept a wide variety of temperature sensors and analog signals.

Note: The use of voltage scale inputs require moving jumpers inside the unit

The DigiRail units are configured over Modbus using a simple Windows utility (included on CD in the box and available from the Novus website). You will need a serial or USB to RS-485 converter to communicate with the unit from a PC.

Features:

  • 2 Analog inputs programmable for thermocouples (J, K, T, E, N, R, S, B), Pt100, mV, V, mA
  • Cold junction compensation for thermocouples and compensation for Pt100 3-wire cables
  • Open loop detection for thermocouples, Pt100 and mV
  • User defined linearisation for the analog inputs
  • LED indicators for communication and status
  • Windows based configurator software.
