Novus Automation offer 3 models of simple RS485 IO module:

  • DigiRail 2A, 2 x universal analogue input MPN 8811100001
  • DigiRail 4C, 4 x digital inputs/counters MPN 8811400101
  • DigiRail 2R, 2 x 8A SPDT relay outputs MPN 8811200101

Devices are DIN rail mounting and require very basic parameter setup using free DigiConfig software. Allowing easy expansion of existing IO and integration as a Modbus RTU Slave, reading and writing the registers accordingly.

The DigiRail line of smart transmitters with Modbus RTU communication interface provide a simple way for integrating analogue or digital signals to supervisory systems. Featuring up to two universal input analogue signal channels they are the most economical way to deliver analogue inputs to PLC´s and SCADA systems. The input signals are isolated from power thus protecting the electrical instruments by eliminating ground loop effects. This reduces substantially the undesirable interferences and instabilities in sensor measurements.

- 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 analog input: 10Hz for mV, V and mA. 5 Hz for t thermocouples and Pt100<
