PEPPERL & FUCHS 039630 - K-System Isolated Barrier - Switch Amplifier with Relay Output
This K-System isolated barrier, model KFD2-CD-EX1.PN, functions as a single-channel switch amplifier designed for the safe operation of intrinsically safe circuits in hazardous areas. It provides galvanic isolation between the input, output, and power supply, converting signals from NAMUR sensors or mechanical contacts into a robust relay output for process control systems. Engineered for critical applications requiring intrinsic safety and reliable signal conditioning.
