Pepperl Fuchs KCD2-STC-Ex1.ES Transmitter Power Supply (322426)
P&F KCD2-STC-Ex1.ES is a 1-channel SMART transmitter power supply offering selectable current or voltage output and line fault detection. Designed for intrinsically safe applications, it powers 2-wire transmitters in hazardous areas and isolates the analog signal into the safe zone. With DIP-switch selectable sink/source modes, HART compatibility, and SIL 3 certification, this barrier is ideal for critical analog signal loops.
