Description
HIMA F7130A — PES H41q Power Supply Module
Product Introduction
Power problems in a legacy safety controller are rarely as simple as replacing a generic 24 VDC supply. The HIMA F7130A is a dedicated power supply module for the PES H41q platform, converting the system’s 24 VDC main supply into regulated 5 VDC rails for the central device, I/O modules, and HIBUS interface. HIMA documents the unit as an electrically isolated DC/DC converter with separate supply connections for the central device/I/O section and HIBUS.
The HIMA F7130A accepts 24 VDC with a specified tolerance of −15% to +20% and provides a 10 A 5 VDC output for the central device/I/O modules plus a separate 1 A 5 VDC HIBUS output. The outputs include current limitation and short-circuit protection. For replacement work, the important point is platform compatibility: F7130A is associated with the H41q architecture, so it should not be treated as a generic 24-to-5 VDC converter.

The electrical values above come from HIMA’s original F7130A documentation. Some secondary listings incorrectly describe this part as a processor, digital input module, or a 24 VDC output power supply; those descriptions conflict with the original HIMA datasheet and should not be used for procurement identification.
Major Features and Engineering Advantages
Dedicated H41q power conversion
is designed around the power requirements of the HIMA PES H41q architecture. Its function is to generate the regulated 5 VDC rails required by the central device and I/O electronics rather than supplying field-level 24 VDC loads.
Separate HIBUS supply
A particularly important detail is the dedicated HIBUS output. HIMA specifies 5 VDC ±0.25 V at up to 1 A for the HIBUS interface, while the central device and I/O modules receive a separate 5 VDC ±0.25 V supply rated at 10 A. This separation should be considered when troubleshooting a system where the CPU/I/O rail appears normal but HIBUS-related operation is abnormal.
F7130A
Galvanic isolation
The uses a DC/DC conversion stage with electrical isolation between input and output. This is significant in a safety-system cabinet because the module is not simply passing the incoming 24 VDC directly onto the internal logic supply.
Protected output stages
HIMA specifies overvoltage protection, current limitation, and short-circuit-proof outputs. These protections help prevent a downstream fault from immediately damaging the power-conversion stage, although they should not be treated as a substitute for checking the actual cabinet wiring and load.
Front-panel diagnostics
The front panel provides LED indication for the incoming L+ supply and the 5 VDC output rails. HIMA notes that normal operation can still be maintained even when the 5 V CPU/EA indicator is only slightly illuminated, so LED brightness alone should not be used as a definitive electrical measurement.
Certified H41/H41q component
HIMA’s certification documentation explicitly lists as a power supply module within its H41/H51/H41q/H51q automation-system module family.
Application Scenarios & Field Pain Points
HIMA PES H41q safety systems
The primary application is the internal power architecture of HIMA PES H41q systems. The module provides the regulated 5 VDC required by the central device and I/O electronics and separately supplies the HIBUS interface.
Legacy safety-system maintenance
is relevant when maintaining older HIMA installations where the original power module has degraded or failed. In this situation, checking the incoming 24 VDC quality is just as important as replacing the module. A marginal DC source can create symptoms that resemble a failed .
CPU and I/O power troubleshooting
If the central electronics repeatedly reset, I/O modules disappear, or the internal 5 VDC rail falls under load, the should be tested under actual system loading rather than judged from an unloaded voltage measurement.
HIBUS-related faults
Because HIBUS has its own 5 VDC output, a fault affecting the bus supply can present differently from a central-device power problem. The separate output architecture is therefore useful when isolating cabinet-level failures.

Engineer’s Guide — Field Pitfalls to Avoid
1. Do not confuse with a 24 VDC output supply.
The documented architecture is 24 VDC input → regulated 5 VDC outputs. Some secondary listings incorrectly describe as providing 24 VDC output. The original HIMA datasheet clearly identifies the output rails as 5 VDC.
2. Verify the H41q platform.
is specifically documented for PES H41q. Do not substitute a visually similar HIMA power module from another generation without checking the rack and system documentation.
3. Check both 5 VDC outputs.
A single measurement of the main 5 V rail is not enough. The central device/I/O supply and HIBUS supply are separate outputs, rated at 10 A and 1 A respectively.
4. Check the 24 VDC source before condemning the module.
The specified input is 24 VDC with a −15% to +20% operating tolerance and ripple below 15%. Excessive ripple or a collapsing upstream supply can produce misleading symptoms.
5. Do not rely only on LED brightness.
HIMA specifically notes that the system can operate correctly even when the 5 V CPU/EA LED illuminates only slightly. Measure the supply electrically and, where appropriate, under system load.
6. Verify the fuse and downstream load after a short-circuit event.
The module has a 5 A gL primary fuse and protected outputs. If the replacement immediately exhibits the same fault, investigate downstream wiring or module loading rather than repeatedly replacing the power supply.
7. Be careful with secondary catalog data.
Public listings contain major contradictions for , including descriptions as a processor, digital input module, 24 VDC supply, and even different input-voltage ranges. The HIMA datasheet is clear: this is a 24 VDC-input, 5 VDC-output power supply module for PES H41q.
FAQ
What is HIMA ?
HIMA is a power supply module for the PES H41q system. It converts a 24 VDC main supply into regulated 5 VDC power for the central device/I/O modules and a separate 5 VDC supply for HIBUS.
What is the input voltage of ?
The nominal input is 24 VDC, with an operating tolerance of −15% to +20% and specified input ripple below 15%.
What are the output ratings?
The main output for the central device and I/O modules is 5 VDC ±0.25 V at 10 A. The separate HIBUS output is 5 VDC ±0.25 V at 1 A.
Is a processor module?
No. The original HIMA documentation identifies as a power supply module. Some online listings incorrectly classify it as a processor or digital I/O module, so procurement should rely on the HIMA documentation and physical nameplate.

What should I verify before purchasing a replacement ?
Verify the complete / 984713060 identification, the H41q system compatibility, physical module markings, 24 VDC input arrangement, both 5 VDC output rails, and actual inventory condition. If the failed unit is being replaced because of a power fault, also test the upstream 24 VDC supply and downstream H41q load before installing the replacement.
