System Compatibility
The FPS400-24 is designed to power the following Foxboro I/A Series components:
- FBM (Field Bus Modules) — all standard analog and digital I/O types
- CP60 / CP270 / CP280 Control Processors
- ZCP270 / ZCP280 Zone Control Processors
- Foxboro SCADA and HMI workstation auxiliary power rails
- Termination Assemblies (TA) and Marshalling Cabinets
Selection Guide
Use the following criteria to confirm the correct power supply for your application:
- Step 1 — Calculate load: Sum the power draw of all FBMs and processors in the cabinet. Add 20% safety margin.
- Step 2 — Verify input voltage: Confirm site AC supply (110 VAC or 220 VAC). The FPS400-24 accepts universal input (85–264 VAC).
- Step 3 — Check DIN rail space: Measure available rail length. The FPS400-24 requires approximately 100 mm of rail width.
- Step 4 — Confirm redundancy requirement: For critical loops, pair two FPS400-24 units with a Foxboro redundancy module (P0922ZU or equivalent).
- Step 5 — Validate certifications: Ensure CE/UL compliance matches your plant’s safety classification (SIL, ATEX zone requirements).

Replacement & Compatibility FAQ
Q: Is the FPS400-24 still in production?
A: The FPS400-24 / P0922YU may be listed as end-of-life by Schneider Electric. Konmask.com maintains stock of new, refurbished, and equivalent units. Contact us for current availability.
Q: Can I use a Phoenix Contact QUINT PSU as a direct replacement?
A: Electrically yes (24 VDC / 20 A output), but mechanical mounting and connector pinout must be verified against your specific cabinet drawing. We recommend a site survey before substitution.
Q: What is the lead time for the original P0922YU?
A: In-stock units ship within 3–5 business days. Out-of-stock orders typically require 4–8 weeks sourcing lead time.
Q: Do you provide a test report with each unit?
A: Yes. A functional test report is included with every shipment upon request.
Q: Can two FPS400-24 units be run in parallel for redundancy?
A: Yes, with the appropriate Foxboro redundancy diode module. Contact us for the correct redundancy kit part number.
