The D1073S converts a mV, RTD, THC, input from temperature sensors, or from Transmitting Potentiometer located in Hazardous Location, and repeats, with isolation, the signal to drive a Safe Area load. Two independent Alarm Trip Amplifiers are also provided. Each alarm energizes or de-energizes an SPST relay for High, Low, Low start-up or Burnout alarm function. Automatic or manual Cold Junction or Line Resistance compensation are standard. All settings are easily programmable via software.

Input from TC with Automatic cold ref. junction compensation, 2,3,4 wire RTD, 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 plus 2 independent set point, 2 SPST Relay contact 2 A / 250 V.

1 channel I.S. input for thermocouples or 3, 4 wire resistance thermometers or transmitting potentiometers, provides 3 port isolation (input/output/supply) and current or voltage output signal. In addition it provides two SPST Relay Alarm contacts with adjustable Alarm Trip Point. 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.

Fully software programmable.
All temperature inputs (mV-TC-RTD-POT-Ohm).
mA or V output.
Built-in double trip amplifier.

D1073S, according IEC 61508 & IEC 61511, is suitable for applications up to safety integrity level SIL 2 .
