HONEYWELL FC-PSU-240516 – Industrial 24 VDC Power Supply for FC-series Controllers and I/O

The HONEYWELL FC-PSU-240516 is a dependable 24 VDC power supply designed to feed Honeywell FC‑series control and safety I/O assemblies, as well as matching field controllers in cabinet installations. From my experience, it’s the kind of PSU you pick when panel uptime, clean power, and straightforward DIN‑rail mounting matter more than bells and whistles. It typically suits brownfield replacements and new control cabinets where a regulated 24 VDC rail (around 5 A) is the standard.

• 24 VDC regulated output (nominal 5 A class) – Stable supply for FC‑series controllers and I/O bases; helps reduce nuisance trips caused by voltage sag.

• Wide-range AC input – Typically accepts global mains (100–240 VAC, 50/60 Hz), making it suitable for multi-site projects.

• Industrial DIN‑rail form factor – Fast TS‑35 mounting; easy to replace during turnarounds or when standardizing cabinets.

• Protection built in – Over‑current, short‑circuit, and over‑voltage protections are usually integrated to safeguard both the PSU and downstream loads.

• Status indication – Front LEDs for quick visual checks; technicians can see output health at a glance.

• Noise‑resilient design – Suits electrically noisy environments common in plants; helps maintain controller stability.

• Ready for redundancy – Commonly used with diode/redundancy modules when higher availability is required.

The FC‑PSU‑240516 is typically used in DCS/PLC cabinets, safety logic panels, and OEM skids where a clean 24 V rail powers FC‑series I/O and controllers. You might notice that it’s frequently specified in:

• Process plants (refining, chemicals, power) where controller uptime and noise immunity are critical

• Water & wastewater stations with compact control panels

• Machine and skid builders standardizing on 24 VDC logic power

• Brownfield upgrades replacing aging supplies without changing the cabinet layout

• Reliability first – Stable 24 VDC helps reduce unexpected controller resets and nuisance faults.

• Compatibility – Matches Honeywell FC‑series power expectations; simplifies engineering and documentation.

• Lifecycle support – In many cases, it aligns with Honeywell’s long‑term spares strategy, easing MRO planning.

• Easy change‑out – DIN‑rail design and front terminals speed up replacement during outages.

• Redundancy‑ready – Pairs well with diode or active redundancy modules for high‑availability cabinets.

One thing I appreciate is how maintenance teams describe it: “Set it and forget it—annual checks only.” That seems to be the common feedback when it’s sized correctly and kept cool.

• Cabinet & mounting – Install on TS‑35 DIN‑rail in a ventilated enclosure. Leave adequate side/top clearance for cooling.

• Wiring – Use appropriately rated copper conductors; keep DC power and signal wiring separated to limit noise coupling. Add a suitably rated upstream breaker or fuse.

• Grounding – Bond protective earth per local codes. Good grounding typically reduces output ripple under load.

• Thermal management – Avoid mounting above high‑heat devices; derate if ambient temperature is elevated.

• Redundancy – For critical loads, consider dual supplies with a diode or active redundancy module and independent mains feeds.

• Routine checks – Annually verify output voltage under load, tighten terminals, and remove dust. No firmware to update on this unit.

Honeywell power supplies in this class are typically CE‑marked and UL‑listed, with RoHS compliance for most regions. Exact approvals can vary by manufacturing revision, so we usually confirm labels and certificates at order time. Standard Honeywell warranty terms (commonly 12 months) apply.

• DIN‑rail redundancy module (for dual‑PSU configurations)

• 24 VDC buffer/UPS module to ride through short outages

• Surge protection device on the AC input

• DC distribution terminal blocks and end clamps

If you’re standardizing a cabinet design or planning a like‑for‑like replacement, share your load current, ambient temperature, and redundancy requirement. We can validate that the FC‑PSU‑240516 fits comfortably with headroom, or suggest a paired redundancy/buffer setup if the application is more demanding.
