https://www.achievers-automation.com More Products
The Pepperl+Fuchs KFD2-SRA-EX4 is a high-reliability 4-channel isolated barrier (switch amplifier) engineered for safe signal transmission between hazardous and non-hazardous areas in industrial automation systems. As a core offering in Pepperl+Fuchs’ trusted KFD2 series, it specializes in converting and isolating digital signals from NAMUR sensors or dry contacts in explosive environments, delivering stable relay outputs to control-side equipment. Its innovative 2:1 wiring technology cuts field wiring requirements by 50% , while integrated line fault detection (LFD) and reversible operation enhance system uptime and flexibility. With a compact 20mm-wide housing and global hazardous area certifications, this module is ideal for space-constrained control cabinets in oil & gas, chemical, and pharmaceutical facilities where safety and efficiency are critical.

Pepperl+Fuchs Automation is our world. Perfect application solutions are our goal.
In 1945, against the backdrop of a war - torn world, Walter Pepperl and Ludwig Fuchs, driven by a strong sense of inventiveness, entrepreneurial foresight, and a deep - seated belief in self - reliance, established a humble radio workshop in Mannheim, Germany.
Their journey was filled with hands - on exploration. As they worked on various radio - related projects, the experiences they amassed became the fertile ground for new and innovative concepts. They took great pleasure in delving into the needs of their customers, constantly striving to develop products that could meet and exceed expectations.
