PRODUCT DESCRIPTION
PEPPERL & FUCHS 231716 - K-System Isolated Barrier, Repeater Power Supply
PEPPERL & FUCHS 231716 is a K-System single-channel isolated barrier and repeater power supply designed for intrinsically safe operation in hazardous areas. It provides galvanic isolation between field devices in Zone 0/1/2 and control systems in the safe area, ensuring reliable signal transmission and compliance with intrinsic safety standards. This module is engineered to power 2-wire NAMUR sensors or mechanical contacts and convert their status into a digital output for process automation applications.
