KCD2-STC-Ex1.2O | Pepperl Fuchs | SMART Transmitter Power Supply
The Pepperl+Fuchs KCD2-STC-Ex1.2O is a single-channel isolated barrier designed to provide power and ensure intrinsic safety for 2-wire SMART transmitters operating in hazardous areas. It transmits the analog input signal as two isolated output signals to the control system in the safe area. A key feature is its support for bidirectional HART communication, allowing for data exchange with SMART field devices. The unit also includes a convenient test socket for connecting a HART communicator without interrupting the loop.
