ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 204132 - K-System Intrinsic Safety Barrier, Switch Amplifier
This K-System intrinsic safety barrier, a two-channel switch amplifier, is engineered for the galvanic isolation and signal conditioning of hazardous area inputs. It facilitates the safe operation of NAMUR sensors or mechanical contacts located in Zone 0, 1, 2, 20, 21, or 22 by providing isolated relay outputs to the safe area. The module integrates line fault detection and a wide power supply range, ensuring robust system reliability in critical process automation applications.
