Pepperl Fuchs KCD2-STC-Ex1.2O Transmitter Power Supply (272955)

P&F KCD2-STC-Ex1.2O is a 1-channel SMART transmitter power supply with dual isolated outputs, designed for powering 2-wire transmitters in hazardous areas. This device functions as a signal splitter, delivering two independent analog outputs in current or voltage form. With DIP-switch configuration, integrated HART test sockets, and SIL 2 compliance, it’s ideal for Ex applications requiring redundant or dual signal routing.
