Product Overview: HIMA F7131 Power Supply Monitoring Module
The HIMA F7131 is a dedicated power supply monitoring module designed for the PES H51q system. It supervises the 5 V system voltage generated by up to three power supplies, providing critical diagnostic feedback through three front-panel LED displays and three test bits for central modules F8650 or F8651. This enables real-time status indication and integration into user programs, ensuring system reliability and rapid fault detection.

Industrial Applications
The HIMA F7131 is essential in safety-critical process industries—such as chemical processing, oil and gas, and power generation—where consistent 5 V supply integrity is mandatory. By detecting voltage dips or failures from any of the three power supplies, it prevents unexpected shutdowns and costly downtime. The three test bits allow logic controllers to respond automatically, while the 24 V outputs enable monitoring of auxiliary power modules when using the B 9361 assembly kit.
Installation Guidance
Mount the HIMA F7131 in a designated slot of the PES H51q rack. Ensure all power supply connections are secure and observe polarity. The front LEDs indicate status: green for normal, red for fault. Connect the test bits to the central modules F8650 or F8651 for diagnostic feedback. For additional power supply integration, wire the three 24 V outputs (PS1–PS3) to the corresponding inputs of the B 9361 kit. No special tools are required, but follow standard ESD precautions.
Maintenance and Battery Replacement
HIMA recommends replacing the CR-1/2 AA-CB battery every four years. Use only HIMA part no. 44 0000016. To replace, power down the system, remove the module from the rack, and swap the battery on the backplane. Reinstall and verify LED status. Regular inspection of the three LED displays helps identify early signs of power supply degradation. Avoid exposing the module to extreme temperatures or humidity.
Selection and Purchasing Advice
Before ordering the HIMA F7131, confirm compatibility with your PES H51q system revision. Verify the required slot width (4 TE) and available power supply capacity. For reliable sourcing, consider PLC Source PRO (store link: ubest101.myshopify.com) which stocks genuine HIMA automation spares. Ensure your application's battery replacement schedule aligns with the four-year interval to maintain uninterrupted monitoring.
