Digital Output Field Termination Assembly Honeywell FC-TSDO-1624

Product Description

The FC-TSDO-1624 is a high-integrity digital output interface engineered by Honeywell for critical Fire & Life Safety (FLS) and Emergency Shutdown (ESD) applications. This 16-channel module forms the decisive link between the safety logic solver and field-mounted protection devices, converting digital commands into high-current electrical outputs to actuate fire dampers, sirens, and suppression equipment.

Designed for uncompromising performance, the FC-TSDO-1624 supports output currents of up to 2 A per channel, enabling it to directly drive heavy inductive loads without interposing relays. With ultra-fast switching latency (≤ 1 ms) and SIL 3 certification, the module ensures safety actions are executed immediately and reliably. It is optimized for Honeywell Safety Manager and Experion PKS systems and supports modern industrial communication protocols for flexible system integration.

Technical Specifications

Strategic Applications

The FC-TSDO-1624 is deployed in environments where rapid, high-current actuation is critical and failure is unacceptable:

• Fire Suppression Systems: Simultaneous activation of high-draw solenoids and deluge valves

• Emergency Signaling: Driving high-power audible alarms and visual strobes across large facilities

• Process Isolation: Fast-acting control of isolation valves in high-pressure or hazardous gas systems

Technical FAQ

How does SIL 3 certification affect system design?
The SIL 3 rating confirms that the FC-TSDO-1624 meets stringent hardware and software safety requirements, allowing its use in high-risk safety loops, provided the complete loop satisfies the required Probability of Failure on Demand (PFD) targets.

Can this module communicate with third-party PLC systems?
Yes. Native support for Ethernet/IP and Modbus TCP/IP enables integration with third-party control systems while maintaining high-speed performance and diagnostic visibility.
