PRODUCT DESCRIPTION
PEPPERL+FUCHS 293717 - K-System Isolated Barrier, Current Driver
The PEPPERL+FUCHS KFD2-CD-EX1.32 is a single-channel, intrinsically safe isolated barrier from the K-System series, engineered for driving current-controlled devices in hazardous area applications. It provides galvanic isolation between the safe area control system and field instrumentation, ensuring signal integrity and explosion protection. This module facilitates the precise control of actuators and positioners from industrial control systems.
