The Pepperl+Fuchs KG30-R/EX-2S is a 2-channel isolated barrier from the K-System, engineered for intrinsic safety applications. This switch amplifier is designed to transfer digital signals, such as those from NAMUR sensors or dry mechanical contacts, from hazardous areas to safe areas. Each channel is equipped with a relay contact output. The device features line fault detection (LFD) to monitor for open or short circuits in the field wiring, ensuring system integrity. With a reversible mode of operation and suitability for applications up to SIL 2 according to IEC 61508, the KG30-R/EX-2S provides a reliable and safe interface for process control systems.
