Product Overview

FC‑PSU‑UNI2450U is high‑capacity 24VDC power feeder unit for Honeywell Safety Manager safety‑instrumented racks. It converts universal AC mains into regulated 24 V DC power to feed safety I/O modules. Redundant parallel deployment eliminates single‑point power failure for SIL‑3 safety loops. Comprehensive hardware protection prevents downstream SIS‑module damage during overload and short‑circuit events. Fault‑relay contact provides power‑supply health status to host system. Mostly supplied as refurbished / new‑old‑stock spare‑parts for oil‑gas and refinery SIS‑system maintenance.

Application Notes

‑ Designed exclusively for Safety Manager SIS racks; do not use for standard DCS Series‑C racks. ‑ Follow Honeywell redundant‑power parallel‑wiring specifications. ‑ Not hot‑swappable for single‑supply configuration; cut AC input before replacement. ‑ Typical deployment: refineries, offshore platforms, chemical‑plants for ESD / F&G safety‑system power‑supply spare‑part stocking.
