Pepperl + Fuchs - KFD0-SCS-EX1.55 CURRENT DRIVER/REPEATER, 30VDC, 1-CHANNEL ISOLATED BARRIER, SCREW TERMINALS, IP20

K-System Isolated Barrier 4-20mA

This reliable SMART current driver repeater Isolated Barrier from Pepperl + Fuchs has been designed for use in intrinsic safe circuits in hazardous applications. Dependable, this Isolation Barrier is loop powered and isolates a 4 mA -20 mA signal for transmitters and positioners and is HART compatible. With a noticeably lower power loss compared to active isolator modules, the barriers 5 V drop makes it suitable for transmitter applications with unstable power sources between 20 V DC and 30 V DC, ideal for numerous intrinsically safe industrial applications.

Line fault detection of the field circuit is possible if the control loop in the safe area is monitored for overscale or underscale conditions of the 4 mA - 20 mA range and features removable terminal blocks. This Isolated Barrier module can also be used for controlling solenoid valves and discrete outputs, such as LEDs. Part of the Pepperl + Fuchs K-System range, this Isolated Barrier is simple to install thanks to its 35mm DIN rail mounting is easy to integrate and expand.
