ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 233469 - K-System Intrinsic Safety Barrier - Switch Amplifier
This K-System intrinsic safety barrier provides galvanic isolation and signal conditioning for hazardous area inputs. It functions as a two-channel switch amplifier, converting signals from NAMUR proximity sensors or potential-free contacts located in Zone 0, 1, or 2 into a single safe area relay output. The module is engineered for robust performance and compliance with intrinsic safety standards in critical process automation environments.
