Features:
- 24 V DC to dual 5 V DC conversion
- Local and redundant outputs rated to 16 A
- Independent overvoltage protection circuits
FS-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 FS-PSU-240516 24 V DC Power Supply Module is available for quotation and technical support from Apter Power.
Verified resources for FS-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.
