Pepperl+Fuchs Intrinsic Safety Barriers SMART Current Driver/Repeater KFD0-SCS-Ex1.55

Signal type: Analog input/analog output


Function: KFD0-SCS-Ex1.55

This isolated barrier is used for intrinsic safety applications. It is loop powered and isolates a 4 mA ... 20mA 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 ... 30 V DC.

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 ... 20mA range.

The module can also be used for controlling solenoid valves and discrete outputs, such as LEDs. In this case, terminals 8- and 9+ are driven with a 24 V signal.


Pepperl+Fuchs offers intrinsically safe Current Drivers as modules of the K-System Isolated Barriers.
