Overview
Configured for AC-to-DC power conversion in Honeywell control and safety system hardware, the Honeywell FC-PSUNI-2424 (FC-PSUNI-2424 Universal Power Supply Module) provides a 24 VDC output for connected automation hardware. It accepts 100 VAC to 240 VAC input at 50/60 Hz and supports output power up to 600 W.
Suffix Breakdown & Model Matrix
The supplied documentation identifies FC-PSUNI-2424 as a complete model designation. No separate suffix or ordering matrix is provided. Therefore, the model string is retained without inferred suffix definitions.

Honeywell Power Conversion and System Integration
The FC-PSUNI-2424 performs AC input conversion to a nominal 24 VDC output for connected control-system hardware. Therefore, installation should separate AC input conductors from low-voltage DC distribution wiring.
The supplied data does not specify 4-20 mA HART, FOUNDATION Fieldbus, Profibus PA, channel-to-channel isolation, or other process-instrument communication functions for this power supply. These functions should not be assigned to the module without a corresponding hardware specification.
The stated 24 VDC output can supply compatible automation equipment within the specified load capability. However, the actual current requirement must remain within the installed power-distribution design and connected-load limits.
Frequently Asked Questions
Q: What input voltage does the FC-PSUNI-2424 accept?
A: The supplied specification states an input range of 100 VAC to 240 VAC at 50/60 Hz.
Q: What DC output does the FC-PSUNI-2424 provide?
A: The module provides a nominal 24 VDC output with output power stated up to 600 W.
Q: Can the FC-PSUNI-2424 be installed on a DIN rail?
A: Yes. The supplied data specifies DIN-rail or panel-mounted cabinet installation.
Field Installation Guidelines
- Verify the AC input range before energizing the module.
- Route AC input wiring separately from 24 VDC distribution conductors where practical.
- Use conductor sizes and protective devices suitable for the actual input and output load.
- Connect the 24 VDC output with correct polarity and verify the connected equipment voltage requirements.
- Provide appropriate cabinet grounding and protective-earth connections according to the installation design.
- Maintain adequate clearance around the power supply for wiring access and thermal dissipation.
- Do not assign IP54 protection to the power supply itself unless the installed housing or cabinet provides that enclosure rating.
- Confirm the actual load current before connecting multiple downstream devices.
- Do not infer hot-swap capability, redundant operation, output isolation, or transient specifications unless they are confirmed by the applicable Honeywell documentation
