PRODUCT DESCRIPTION
PEPPERL & FUCHS 115933 - Intrinsic Safety Barrier Switch Amplifier
The PEPPERL & FUCHS 115933 is a K-System intrinsic safety barrier and switch amplifier, providing galvanic isolation for signal transmission from hazardous areas. It facilitates the connection of NAMUR proximity sensors or mechanical contacts, converting their status into two independent, potential-free relay outputs for control systems in safe areas. This module is engineered for functional safety applications, featuring line fault detection and configurable switching logic.
