It converts a 24 V DC primary supply into a stabilized 5 V DC output for internal electronics and system backplane power distribution.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eIt 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.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable class=\"w-fit min-w-(--thread-content-width)\"\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003cth class=\"\"\u003eParameter\u003c\/th\u003e\n\u003cth class=\"\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eF 7126\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHIMA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eGermany\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eNot specified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e8 TE module width\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e24 V DC input, max 6.3 A fuse protected\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eTechnical FAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the main function of F 7126 module?\u003c\/strong\u003e\u003cbr\u003eIt converts 24 V DC input into regulated 5 V DC system power for H51q controllers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan F 7126 be used in redundant configuration?\u003c\/strong\u003e\u003cbr\u003eYes, but output voltage balancing within 0.025 V is required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the module provide electrical isolation?\u003c\/strong\u003e\u003cbr\u003eYes, it includes safe galvanic isolation between input and output stages.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the output protected against short circuits?\u003c\/strong\u003e\u003cbr\u003eYes, the output is fully short circuit protected with internal current limitation.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eEngineering \u0026amp; Installation Guide\u003c\/h3\u003e\n\u003cp\u003eInstall the F 7126 module inside certified HIMA rack systems only.
