The DigiRail line of smart transmitters with Modbus RTU comunication interface provide a simple way for integrating analog or digital signals to supervisory systems. Featuring up to two universal input analog signal channels they are the most economical way to deliver analog 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
• Analog input resolution: 17 bits
Digital inputs: in voltage, 4 to 35 V to activate. Internally limited current in 5 mA
Digital outputs: 8 A / 250 Vac SPDT relay, resistive load
Power: 10 to 35 Vdc,  50 mA maximum current
2-wire RS485 communication with Modbus RTU protocol. Configurable address and
baud rate (1,200 to 115,200bps)
LED indicators for communication and status
Key for resetting communication parameters to original factory default
Accuracy (at 25 °C): Pt100, mV, V and mA: ±0.15 % of full scale. Thermocouples:
