SIL 2 TEMPERATURE SIGNAL CONVERTER, MULTIFUNCTION, TRIP AMPLIFIERS
DESCRIPTION
The single channel Temperature Signal Converter, Trip amplifiers D5273S 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 (according to IEC 61511) in safety related systems for high risk industries. Output signal can be direct or reverse. Output function can be configured as: Adder, subtractor, low/high selector. Modbus RTU RS-485 output is available on Bus connector. Cold junction compensation can be programmed as automatic, using an internal temperature sensor or fixed to a user-customizable temperature value.
D5273S offers two independent trip amplifiers via two SPDT output relays.
Mounting on standard DIN-Rail, with or without Power Bus, in Safe Area / Non Hazardous Location or in Zone 2 / Class I, Division 2 or Class I, Zone 2.
