Honeywell FC-TRO-0824 (FC-TSRO-0824) 8-Channel Safety Relay Output FTA

Product Description

The FC-TRO-0824 (full part number FC-TSRO-0824) is an 8-channel relay contact field termination assembly for Honeywell Safety Manager SIS (Safety Instrumented System). It receives safety logic commands from the safety controller, drives dry relay contacts for ESD, shutdown valves, fire and gas alarm outputs. It supports SIL3 safety certification, with built-in relay contact and wiring fault diagnostics, widely used in petrochemical and refinery safety interlock cabinets.

FAQ

Q: What is the difference between FC-TRO-0824 and FC-TSDO-0824?
A: FC-TRO-0824 is relay dry contact output FTA; FC-TSDO-0824 is solid-state digital output FTA without relay contacts.

Q: Which system does it belong to?
A: Honeywell Safety Manager SIS safety system, compatible with Experion PKS safety control architecture.

Q: Is this module discontinued?
A: Safety Manager series is legacy SIS hardware, original production stopped, supplied as surplus, refurbished and tested spare parts only.

Q: Can it be used directly without safety controller?
A: No, it is only a termination relay FTA, must cooperate with Safety Manager logic solver to execute safety trip logic.
