PRODUCT DESCRIPTION
PEPPERL & FUCHS 228631 - KFD2-CD-EX1.32 Isolated Barrier, Control Circuit Device
This device is an isolated barrier from the K-System series, engineered for controlling intrinsically safe loads in hazardous areas. It provides galvanic isolation between the safe area control system and field devices such as solenoid valves or I/P converters, ensuring intrinsic safety compliance. The unit features line fault detection and is suitable for safety instrumented systems up to SIL 2.
