Features:

  • 24 V DC to dual 5 V DC conversion
  • Local and redundant outputs rated to 16 A
  • Independent overvoltage protection circuits
FC-PSU-240516 supplies regulated backplane power for Safety Manager processor and I/O hardware from the cabinet 24 V DC source.

Correct load calculation, cable sizing, grounding and airflow are essential to reliable service.

Input voltage, both 5 V output rails and redundancy indications should be checked at normal chassis load before the supply is accepted for service.

The Honeywell FC-PSU-240516 24 V DC Power Supply Module is available for quotation and technical support from Apter Power.
Verified resources for FC-PSU-240516:

Power Data:

  • 24 V DC input, -15%/+30%
  • Less than 6 A input at full 16 A load
  • Inrush current below 5 A
Measure the supply at the module terminals to include cable and protection-device voltage drop.

Output Loads:

  • Local 5 V rail: 0.5–16 A
  • Redundant 5 V rail: 0.5–16 A
  • Calculate loads from installed module ratings
Do not commission the PSU until both output budgets have adequate margin.

Redundancy:

  • Separate local and redundant paths
  • Two independent overvoltage circuits
  • Review current sharing and partner supply status
The complete chassis power design determines whether redundant operation is achieved.

Installation Check:

  • Verify polarity and protective devices
  • Check 5 V rails before loading
  • Confirm cooling and controller diagnostics
Record supply voltages and alarms after the chassis reaches normal operating load.
Description
Honeywell FC-PSU-240516 24 V DC Power Supply Module is the conformal-coated 24 V DC Power Supply Module for Honeywell Safety Manager. It converts the cabinet input supply into regulated local and redundant 5 V DC outputs used by processor and I/O hardware in the controller chassis.

The documented input range is 24 V DC at -15% to +30%, with input current below 6 A at a 16 A load and inrush current below 5 A. Both the local and redundant 5 V outputs support loads from 0.5 A to 16 A and are supervised by two independent overvoltage-protection circuits.

Before installing the PSU, calculate the demand on both 5 V rails and verify input polarity, protective devices, cable capacity, backplane connections and cabinet cooling. After energization, measure both output rails under normal load and confirm that controller power and redundancy diagnostics remain clear.

Technical notes
FC-PSU-240516 converts 24 V DC input to regulated local and redundant 5 V DC outputs for Honeywell Safety Manager hardware. Verify both output loads and overvoltage-protection status before energizing the chassis.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How should the 5 V load be checked for FC-PSU-240516?
Add the documented current demand of every powered module on the local and redundant rails and keep each output within the 0.5–16 A range.
What input range is permitted for FC-PSU-240516?
The nominal input is 24 V DC with a documented tolerance of -15%/+30%; verify cabinet voltage at the module terminals under load.
Why does FC-PSU-240516 provide local and redundant outputs?
Separate output paths support the Safety Manager power architecture and allow the engineered redundant supply arrangement to be maintained.
What does the dual overvoltage protection protect against?
Two independent circuits supervise excessive output voltage so a single protection fault does not remove the intended protection layer.
What can cause repeated PSU shutdown or alarm?
Check 24 V input sag, excessive 5 V load, short circuits, poor backplane connections, cooling and overvoltage-protection diagnostics.
Can FS-PSU and FC-PSU versions be swapped directly?
Only if the project permits the coating change; verify approvals, environment and installed hardware configuration before substitution.
Which checks are needed after replacing FC-PSU-240516?
Measure input and both 5 V rails, confirm current sharing or redundancy, review controller alarms and test all affected chassis modules.
What information is needed to quote FC-PSU-240516?
Provide the exact model, chassis configuration, total local and redundant loads, coating requirement, installed revision, quantity and destination.
