PRODUCT DESCRIPTION
PEPPERL & FUCHS 021030 - K-System Single-Channel Switch Amplifier with Safety Relay Output
This K-System intrinsically safe barrier is a single-channel switch amplifier designed for reliable signal conditioning and switching in hazardous area applications. It provides galvanic isolation between the intrinsically safe input circuit (Zone 0, 1, 2) and the non-intrinsically safe output circuit, featuring two normally open (NO) relay contacts for control system integration. Engineered for safety instrumented systems, it offers line fault detection and is certified for use up to Safety Integrity Level (SIL) 2.
