PRODUCT DESCRIPTION
PEPPERL & FUCHS 131622 - K-System Intrinsic Safety Barrier Repeater Power Supply
This K-System intrinsic safety barrier provides galvanic isolation and signal conditioning for NAMUR sensors or mechanical contacts located in hazardous areas. It functions as a repeater power supply, delivering intrinsically safe power to the field device while transmitting a safe, conditioned signal to the control system via a relay output. Engineered for process automation applications requiring compliance with intrinsic safety standards and functional safety up to SIL 2.
