Compatible Replacement & Equivalent Models
The table below lists functionally equivalent or drop-in replacement options. Always verify electrical ratings and backplane compatibility before substitution.
| Part Number | Brand | Compatibility Notes | Type |
|---|---|---|---|
| FC-TPSU-2430 | Honeywell | Direct OEM variant — same platform, 24 V / 30 A output | OEM Variant |
| FC-PSU-UNI2450U | Honeywell | Universal input version; wider AC/DC input range | OEM Variant |
| FC-PSU-240516E | Honeywell | Enhanced version with extended diagnostics (check firmware) | Upgraded OEM |
| 51204172-175 | Honeywell | Legacy Safety Manager PSU — verify chassis slot compatibility | Legacy OEM |
| Third-party 24 VDC / 16 A DIN PSU | Various | Functional substitute for non-SIL applications only; not certified for Safety Manager | Functional Substitute |
⚠ Note: For SIL-rated safety loops, only OEM Honeywell modules are certified. Third-party substitutes are suitable for non-safety auxiliary power circuits only.
Why Choose the Original Model
- SIL 2/3 Certification: Maintains functional safety integrity required by IEC 61511 / IEC 61508.
- Seamless Integration: Plug-and-play with Honeywell Safety Manager and Experion PKS backplanes — no firmware changes required.
- Redundancy Support: Supports N+1 redundant PSU configurations for continuous process availability.
- OEM Diagnostics: Full health monitoring via Honeywell’s FDM / Station software.
- Long-term Support: Covered under Honeywell’s lifecycle and spare-parts program.
Typical Applications
- Oil & gas safety instrumented systems (SIS)
- Chemical and petrochemical DCS power distribution
- Power generation plant control systems
- Offshore platform safety and control cabinets
- Pharmaceutical batch control systems
- Water treatment and utilities automation
System Compatibility
| Platform | Compatible | Notes |
|---|---|---|
| Honeywell Safety Manager (SM) | ✅ Yes | Primary target platform |
| Honeywell Experion PKS / FS | ✅ Yes | Verify chassis generation (C300 / C200) |
| Honeywell TDC 3000 | ⚠ Check | Legacy platform — consult Honeywell engineering |
| Third-party DCS (ABB, Emerson, Siemens) | ❌ No | Not compatible — platform-specific module |
Selection Guide
Use the following decision tree to select the correct PSU model for your application:
- Identify your platform: Safety Manager vs. Experion PKS/FS — both are supported, but chassis slot assignments differ.
- Determine output requirement: Need 24 V / 16 A → FC-PSU-240516; need 24 V / 30 A → FC-TPSU-2430; need universal AC/DC input → FC-PSU-UNI2450U.
- Check redundancy: If N+1 redundancy is required, order a matching second unit and verify the chassis supports dual-PSU slots.
- Confirm SIL requirement: Safety loops → OEM only. Non-safety auxiliary circuits → functional substitutes may apply.
- Verify firmware compatibility: For enhanced variants (FC-PSU-240516E), confirm your Safety Manager firmware version supports extended diagnostics.

Replacement & Compatibility FAQ
Q: Can FC-TPSU-2430 replace FC-PSU-240516 directly?
A: They are OEM variants on the same platform. The FC-TPSU-2430 provides higher output current (30 A vs. 16 A). It can replace FC-PSU-240516 in most chassis slots, but verify slot power budget and backplane rating.
Q: Is FC-PSU-UNI2450U suitable for 110 V AC sites?
A: Yes. The UNI2450U features a universal input range (85–264 V AC / 100–350 V DC), making it ideal for mixed-voltage facilities.
Q: Can I use a generic 24 V DIN-rail PSU as a replacement in a Safety Manager system?
A: Only for non-SIL auxiliary circuits. Safety-rated loops require certified OEM modules to maintain SIL integrity per IEC 61511.
Q: What is the difference between FC-PSU-240516 and FC-PSU-240516E?
A: The “E” variant adds extended diagnostics and may require a minimum Safety Manager firmware version. Confirm with Honeywell engineering before substitution.
Q: Do you provide test reports or certificates of conformance?
A: Yes — available on request for all units. Contact support@konmask.com.
