ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 70133052 - K-System Isolated Barrier Switch Amplifier
This device is a two-channel isolated barrier from the K-System series, engineered for the safe operation of intrinsically safe circuits in hazardous areas. It functions as a switch amplifier, providing galvanic isolation between the hazardous and non-hazardous areas while converting input signals from NAMUR sensors or mechanical contacts into isolated relay outputs for control system integration. Its primary application is in process automation for monitoring limit switches, proximity sensors, and emergency stop buttons in potentially explosive atmospheres.
