D1072
- SIL 2 Temperature Signal Converter, Duplicator, Adder/Subtractor
G.M. International ISM0018-13
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.
Function:
1 or 2 channel I.S. input from mV, thermocouples, 3-4 wires resistance thermometers, transmitting potentiometers, provides 3 port isolation (input/output/supply) and current
(source mode) or voltage output signal. Duplicator, adder, subtractor, low/high selector function provided. The programmable RTD line resistance compensation allows the use of
2 wires RTDs or error compensation for 3-4 wires RTDs. Reference junction compensation can be automatic, with option 91, or fixed by software setting.
Signalling LEDs:
Power supply indication (green), burnout (red).
Configurability:
Totally software configurable, no jumpers or switches, input sensor, connection mode, burnout operation, mA or V output signal, by GM Pocket Portable Configurator
PPC1090, powered by the unit or configured by PC via RS-232 serial line with PPC1092 Adapter and SWC1090 Configurator software. A 16 characters tag can be inserted using
SWC1090 Configurator software. To operate PPC1090 or PPC1092 refer to instruction manual.
