PRODUCT DESCRIPTION
PEPPERL & FUCHS 3261610183 - Intrinsic Safety Barrier, Switch Amplifier
The PEPPERL & FUCHS 3261610183 is a K-System series intrinsic safety barrier, specifically a two-channel switch amplifier, designed for reliable signal transmission from hazardous areas to safe area control systems. It provides galvanic isolation and processes signals from NAMUR sensors or mechanical contacts, outputting potential-free relay contacts for process control and safety instrumented systems.
