General Description:
The single and dual channel DIN Rail Temperature Signal Converter D1072S and
D1072D accepts a low level dc signal from millivolt, thermocouple or RTD temperature
sensor, located in Hazardous Area, and converts, with isolation, the signal to drive a
Safe Area load. Output signal can be direct or reverse.
Duplicator function provides two independent outputs for the single input.
Adder, subtractor, low/high selector functions provides two independent outputs
representing input A, input B, input A plus input B, input A minus input B,
low/high selector.
