F 7126 (F7126) is a regulated DC/DC power supply module designed for HIMA PES H51q safety control systems. It converts a 24 V DC primary supply into a stabilized 5 V DC output for internal electronics and system backplane power distribution.
This module is widely used in safety instrumented systems across oil and gas, power plants, chemical processing, and industrial automation facilities. It ensures stable voltage supply for safety controllers under fluctuating field power conditions. The design supports continuous operation in redundant configurations where output stability directly impacts system availability.
The internal architecture includes safe galvanic isolation between input and output circuits. It integrates overvoltage protection, current limitation, and short circuit protection to maintain stable operation under electrical fault conditions. Engineers use this module to improve system reliability and reduce downtime caused by unstable control power rails.
The F 7126 module operates as a high efficiency DC/DC converter with isolated input and regulated output stages. It converts a nominal 24 V DC supply into a precise 5 V DC system voltage for H51q PES electronics.
The module supports redundant operation, where two units operate in parallel. Output balancing is required, and voltage deviation must remain within 0.025 V to prevent load imbalance.
It includes integrated overvoltage protection and current limiting behavior. In fault conditions, the output remains short circuit proof and transitions into protective shutdown behavior. Front panel access allows voltage adjustment and test measurement during commissioning.

What is the main function of F 7126 module?
It converts 24 V DC input into regulated 5 V DC system power for H51q controllers.
Can F 7126 be used in redundant configuration?
Yes, but output voltage balancing within 0.025 V is required.
Does the module provide electrical isolation?
Yes, it includes safe galvanic isolation between input and output stages.
Is the output protected against short circuits?
Yes, the output is fully short circuit protected with internal current limitation.
Install the F 7126 module inside certified HIMA rack systems only. Ensure correct backplane seating and secure mechanical fixation to avoid vibration stress.
Maintain proper grounding of the system rack to reduce electrical noise and improve signal stability. Use shielded power cables and avoid routing near high frequency switching equipment.
Ensure sufficient cabinet ventilation to maintain operating temperature within 60 deg C. Avoid installing near high heat dissipation modules or power transformers.
Verify correct fuse protection on the 24 V DC supply line before commissioning. In redundant setups, calibrate output voltage difference carefully to avoid load imbalance.
