The Temperature Converter & Trip Amplifier D5274 accepts a low level dc signal from millivolt/thermocouple or 2-3-4 wire resistance/RTD or 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. Front trimmers allow easy zero & span current adjustment. Cold junction compensation can be programmed as automatic, using an internal or external temperature sensor or fixed to a user customizable temperature value. D5274S offers two independent trip amplifiers via two SPDT output relays, whose thresholds are fully programmable. Extended power supply range guarantees functionality at 24 Vdc as well as 12 Vdc nominal voltage.
