Product Overview

FC‑RUSIO‑3224 is remote universal safety I/O module for Honeywell Safety Manager SIS safety‑instrumented systems. It provides 32 configurable safety‑rated I/O channels for remote‑located field‑I/O cabinets, reducing long‑distance field‑cable runs from main SIS control room. Supports safety‑critical discrete and analog safety‑loop signals including HART smart safety transmitters. It communicates with main Safety‑Manager CPU over safety‑bus link. Full channel‑level diagnostics report wiring and module‑hardware faults to safety system. OEM production discontinued; available as refurbished / new‑old‑stock spare‑parts for ESD, fire‑and‑gas safety‑system retrofits.

Application Notes

‑ Requires matching remote‑I/O chassis and safety‑bus communication link; verify firmware revision compatibility. ‑ Not hot‑swappable; cut module 24VDC supply before replacement. ‑ Install inside well‑ventilated remote field cabinet; avoid corrosive‑gas and condensation exposure. ‑ Typical deployment: oil‑gas on‑site remote safety‑I/O cabinets, refineries, chemical‑plants SIS spare‑part stocking.
