KFD2-ER-EX1.W.LB Pepperl+Fuchs 217732 Conductive Liquid Level Switch Safety Barrier
The Pepperl+Fuchs KFD2-ER-EX1.W.LB (Order No. 217732) is a DIN rail-mounted, intrinsically safe output relay module designed for reliable and secure switching of loads in explosive atmospheres (Zone 0/20 and Zone 1/21). As part of the trusted K-System safety barrier portfolio, this device provides galvanic isolation, explosion protection, and plug-in relay functionality for use in process automation, oil & gas, chemical plants, pharmaceutical manufacturing, and other industries requiring ATEX and IECEx compliance.
This module accepts a non-intrinsically safe control signal from a PLC or DCS and drives an intrinsically safe relay contact output, enabling safe actuation of field devices such as solenoid valves, alarms, or small actuators located in hazardous zones. With its changeable miniature relay, LED status indicators, and low power consumption, the KFD2-ER-EX1.W.LB ensures both operational safety and ease of maintenance.
