PRODUCT DESCRIPTION
PEPPERL & FUCHS 800117 - K-System Safety Relay Output Barrier
This K-System safety barrier, identified by internal code 800117, is a dual-channel switch amplifier engineered for intrinsic safety applications in hazardous areas. It provides galvanic isolation between field devices in Zone 0, 1, or 2 and control systems in the safe area, converting NAMUR proximity sensor or switch inputs into two independent relay outputs. Designed for process automation, it ensures reliable signal transmission and safety integrity up to SIL 2.
