The KCD2-SR-EX2 belongs to ’ K-system product lineup, renowned for its compact design, high safety performance, and easy integration into industrial control panels. As a 2-channel isolated barrier, it is specifically designed for intrinsic safety applications, capable of transmitting digital signals from NAMUR sensors or mechanical contacts in hazardous areas to safe area control systems. It features galvanic isolation between input, output, and power supply, preventing noise, potential differences, or transients from the hazardous area from affecting safe area circuits.
Key features of the KCD2-SR-EX2 include 2-channel isolated design, dry contact or NAMUR inputs, relay contact outputs, and line fault detection (LFD) that can be enabled or disabled via a DIP switch. The barrier also boasts a compact 12.5 mm wide housing, IP20 protection rating, and compliance with SIL 2 (IEC 61508) safety standards, making it suitable for space-critical and high-safety industrial applications. As part of ’ proven product lineup, it adheres to international quality and safety standards, reflecting the brand’s commitment to engineering excellence and reliable intrinsic safety solutions.

Brand
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.
