    FAQs

    Q1: What is the primary function of the FC-RUSLS-3224?

    It is a 32-channel Safety Manager Remote I/O Logic Solver Module that executes safety logic and processes field signals for safety instrumented functions. It is certified to SIL 3 and designed for Honeywell's Safety Manager platform, providing safety logic solving and I/O interface for ESD, F&G, and BMS applications.

    Q2: Is the FC-RUSLS-3224 still in production?

    No. This module was discontinued by Honeywell in 2018. It is no longer manufactured and is available only through aftermarket suppliers as legacy/spare-part stock. Honeywell recommends migrating to the FC-RUSIO-3224 (Universal Safety I/O Module) or the newer Safety Manager SC platform for new installations.

    Q3: What is the difference between FC-RUSLS-3224 and FC-RUSIO-3224?

    The FC-RUSLS-3224 is the legacy SM RIO Logic Solver Module (discontinued 2018). The FC-RUSIO-3224 is the Universal Safety I/O Module (active product) that provides more flexibility with configurable analog/digital channels and HART pass-through. The RUSIO-3224 is the recommended replacement for the RUSLS-3224 in legacy system upgrades.

    Q4: What terminal assembly (IOTA) is required for this module?

    The FC-RUSLS-3224 requires a compatible IOTA (I/O Terminal Assembly) for field wiring. Compatible options include:

    • FC-IOTA-NR24: Non-Redundant IOTA

    • FC-IOTA-R24: Redundant IOTA

    Q5: Can the FC-RUSLS-3224 be hot-swapped?

    Yes, the module supports hot-swap capability when used in a properly configured redundant Safety Manager system. This allows replacement during system operation without interrupting the safety instrumented function. However, due to its discontinued status, maintaining spare inventory is strongly recommended for critical installations.
