    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.


    Input (each input programable): Output:
    J, K, T, E, N, R, S, B Thermocouples Modbus RTU
    Pt100 RS-485
    0 to 50 mV 1,200 to 115,200 bps
    0 to 20 mV E/O/N parity
    -10 to 20 mV  
    0 to 5 V ¹  
    0 to 10 V ¹ Power:
    0 to 20 mA 10 to 35 VDC
    4 to 20 mA ≤50 mA

    Note 1: 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.


    • 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
    • Sampling rate for 1 analogue input: 10Hz for mV, V and mA. 5Hz for thermocouples and Pt100
    • Electrical isolation between inputs and supply/serial ports: 1000Vac
    • 17 bit analog input resolution
    • User defined linearisation for the analog inputs
