PRODUCT DESCRIPTION
PEPPERL & FUCHS 220355 - K-System Intrinsic Safety Barrier - Switch Amplifier
This is a 2-channel intrinsic safety barrier from the K-System series, engineered to provide galvanic isolation and signal conditioning for hazardous area applications. It converts signals from NAMUR proximity sensors or dry contacts located in hazardous areas into safe, isolated relay outputs for control systems in the safe area. The device incorporates line fault detection and is certified for use in safety instrumented systems up to SIL 2.
