    Terms and Conditions



    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
    • 10 to 35 VDC powered, 50 mA maximum current
    • 2-wire RS485 communication with Modbus RTU protocol. Configurable address and baud rate (1,200 to 115,200 bps)
    • LED indicators for communication and status
    • Accuracy (at 25°C): Pt100, mV, V and mA: ±0.15% of full scale. Thermocouples: ±0.25% of full scale.
    • Temperature effect: 0.003% of full scale/°C.
    • Cold junction compensation for thermocouples: 1°C at 25°C. ±0.05°C/°C
    • 1000 VAC isolation from inputs (analogue or digital) and power or communication.
    • Windows based configurator software.
    • Dimensions: 72 × 78 × 19 mm.
    • Mounts on standard 35 mm DIN rail.
    • Working temperature: 0 to 70 °C.
