GMI D5273S I.S. SIL2 Temperature Converter & Trip Amplifier Intrinsically Safe Isolators

DESCRIPTION

The Temperature Converter & Trip Amplifier D5273 accepts a low level dc signal from millivolt, thermocouple or 2-3-4 wire RTD or transmitting potentiometer sensors, located in Hazardous Area, and converts, with isolation, the signal to drive a Safe Area load, suitable for applications requiring SIL 2 level in safety related systems for high risk industries. Output signal can be direct or reverse. Modbus RTU RS-485 output is available on Bus connector. Cold junction compensation can be programmed as Internal: provided by an internal PT1000 sensor; Fixed: to a user-customizable temperature value; External remote: ext. RTD placed away, on a support terminal board; External local: ext. RTD placed close to the module terminal block. D5273S offers two independent trip amplifiers via two SPDT output relays.
