HIMA F-PWR02 – Redundant 24 VDC Power Supply Module for F‑series Safety Systems
The HIMA F-PWR02 is a dedicated power supply module designed to feed HIMA F‑series safety controllers and I/O racks with stable 24 VDC. From my experience, it’s typically used to build high-availability power pairs in H41q/H51q and related F‑system cabinets, keeping the backplane powered while allowing maintenance without risking a process trip. You might notice that most teams adopt it in redundant configurations, especially where continuous operation and TÜV-certified safety loops are a must.

Key Features
- 24 VDC System Supply – Provides the regulated 24 VDC required by HIMA F‑series racks; engineered for steady backplane power.
- Redundancy Support – Typically installed in pairs for 1oo2 power availability; seamless switchover in the event of a module or feed issue.
- Diagnostics & Front LEDs – Clear status indication makes it easy to verify healthy operation at a glance during rounds.
- Protected Inputs – Overcurrent and overvoltage protection help safeguard the controller and I/O base.
- Backplane Integration – No external I/O; communicates health over the system bus, which keeps wiring simple and tidy.
- Service-Friendly – In many cases it can be replaced with minimal process impact when used in a redundant setup.
Quick field note: A refinery client told us the F-PWR02 “behaved exactly as expected” during a planned power switchover test—no nuisance trips, just a clean transfer to the standby unit. That’s typically what operators want to see before a turnaround.

Related and Supporting Products
- HIMA F-PWR01 – Earlier/alternative power module variant used on certain F‑series racks; check capacity and compatibility per system manual.
- HIMA X-PM 01 (HIMax) – Power module for HIMax platforms; a better fit if your system is HIMax rather than H41q/H51q.
- HIMA F‑series Racks/Backplanes – Required housing for the F-PWR02; choose the slot count to match controller and I/O population.
- 24 VDC Industrial Power Feed with Redundant Diodes – External supply/UPS recommended to feed the module pair for higher availability.
Installation & Maintenance
- Cabinet & Environment – Install in a clean, dry control cabinet meeting industrial standards (IP54 or better is typical). Provide front‑to‑back ventilation and maintain ambient within the stated temperature range.
- Wiring – Use properly sized 24 VDC feeds with segregated routing from high‑noise cables. Tighten terminal torque to spec and label A/B redundant supplies clearly.
- Redundancy Setup – For critical loops, deploy two F-PWR02 modules fed from independent 24 V sources or UPS channels. Verify switchover logic per site FAT/SAT procedure.
- Safety – De‑energize the feed when working on a single unit unless tested procedures allow hot maintenance within a redundant pair. Follow lockout/tagout and site policies.
- Routine Care – Quarterly visual checks for connector seating and LED status; annual cleaning of dust with ESD‑safe methods; document firmware or revision info if applicable and keep spares sealed.
- Verification – After replacement, perform a quick health check on the system diagnostics and confirm load sharing or standby readiness.
