The Honeywell FS-16DI-RL, also cataloged as the FS-16DI-RL Relay Input Terminal Board, serves as the primary termination interface for discrete relay input signals across Honeywell Safety Manager and Experion PKS platforms. It provides 16 input channels with defined current-limited paths for safe acquisition.

Channel-to-Channel Isolation
The FS-16DI-RL employschannel-to-channel isolation to prevent cross-talk between relay input signals. Each channel is electrically separated, ensuring that short-circuit or overload conditions remain localized. This design supports high-integrity signal acquisition in Honeywell control and safety systems.
Frequently Asked Questions
Q: Can the FS-16DI-RL be hot-swapped during operation?
A: Hot-swap is supported when input circuits are isolated; relay contacts must be de-energized before removal or insertion.
Q: How does the module handle overload detection?
A: Internal current limiting ensures safe shutdown of affected channels without impacting system backplane integrity.
Q: Is firmware upgrade required for integration?
A: No firmware upgrade is required; the board functions as a passive termination interface.
