SIL 2 Temperature Signal Converter, Multifunction, Trip Amplifiers


The single channel Temperature Signal Converter, Trip amplifiers D6273S accepts a low level dc signal from millivolt, thermocouple or 2-3-4 wire RTD or transmitting potentiometer sensors, and converts, with isolation, the signal to drive a 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.
D6273S offers two independent trip amplifiers via two SPDT output relays.
Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards.
