Overview of Pepperl+Fuchs KCD2-STC-Ex1 SMART Transmitter Power Supply

 

Isolated Intrinsic Safety Barriers

Solving a wide range of applications in one system, our K-System barriers guarantee a reliable and economical signal transmission between your field device and the control system. Whether your plans include a single isolating module or a large scale system integration we have comprehensive offering of galvanically isolated interface modules suitable for Division 1/2 hazardous ‘classified’ locations. They are suitable for a wide range of analog and discrete circuits and signal conditioning applications including switches, proximity sensors, transmitters, I/P converters, TC/RTDs, potentiometers, solenoids, over/under speed and frequency conversion. Isolated barriers are used for intrinsic safety application.
