PRODUCT DESCRIPTION
PEPPERL & FUCHS 126087 - K-System Intrinsic Safety Barrier, Switch Amplifier
This K-System intrinsic safety barrier, identified as KFD2-CD-EX1.32, provides galvanic isolation and signal conditioning for operating intrinsically safe loads in hazardous areas. It functions as a switch amplifier and solenoid driver, enabling the control of actuators such as solenoid valves or sounders from a safe area control system while ensuring compliance with explosion protection standards.
