- Signal conditioning and digital transmitter
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 ...
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. 5Hz
for t thermocouples and Pt100.
Analog input resolution: 17 bits.
linearization for the analog inputs.
Digital inputs: in voltage, 4 to 35V to
activate. Internally limited current in 5mA.
Digital outputs: 3A / 250Vac SPDT
relay, resistive load.
Power: 10 to 35Vdc, 50mA maximum current.
RS485 communication with Modbus RTU protocol. Configurable address and baud rate
(1,200 to 115,200bps).
LED indicators for communication and status.
for resetting communication parameters to original factory default.
(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.
junction compensation for thermocouples: 1°C at 25°C. ±0.05°C/°C.
