2 Ch, Temperature Signal Converter, Duplicator, Selector, Adder, Subtracter, SIL 2

12-24 Vdc

2

The D1072D converts two mV, RTD, TC, inputs from temperature sensors, or from Transmitting Potentiometers located in Hazardous Location, and repeats, with isolation, the two isolated signals to drive two independent Safe Area loads. Output Signals can be direct, duplicated, the sum or the difference of the two inputs, or the higher-lower selection of the two inputs. Automatic or manual Cold Junction or Line Resistance compensation are standard. All settings are easily programmable via software.
Approved for Div. 2 installation

Input from TC with automatic cold junction compensation, 2,3,4 wire RTD, or Transmitter Potentiometer with burnout indication.

4-20 mA/0-20 mA or 1-5 V/0-5 V or 2-10 V/0-10 V output signal totally isolated from Input and Supply.

2 channels I.S. input from millivolt, thermocouples or 3, 4 wire resistance thermometers or transmitting potentiometers, provides 3 port isolation (input/output/supply) and current or voltage output signal. Duplicator, adder, subtractor, low/high selector. The programmable RTD line resistance compensation allow use of 2 wire RTDs or error compensation for 3-4 wire RTDs. Cold Junction compensation can be automatic, with option 91, or fixed by software setting.

High density with 2 independent channels.
Fully software programmable.
All temperature inputs (mV-TC-RTD-POT-Ohm).
mA or V output.
Signal duplicator retaining i.a. approval.
Signal selector (high-low) or adder or subtracter
Automatic or Manual CJC.
Resistance line compensation.

D1072D, according IEC 61508 & IEC 61511, is suitable for applications up to safety integrity level SIL 2 .
