Overview
The KCD2-STC-EX1 Smart Transmitter Power Supply from Pepperl+Fuchs is part of the K-System DIN-rail mounting series. It provides a 24 V DC supply via Power Rail to energize 2-wire SMART transmitters or current sources in hazardous areas. Moreover, it repeats the input signal to the safe area as either a 4–20 mA current loop or a 1–5 V voltage signal, ensuring accurate and reliable transmission to control systems. In addition, the module supports HART® communication, enabling digital diagnostics and device configuration over the analog loop.
Engineers value the KCD2-STC-EX1 for its compact 12.5 mm housing width and its functional safety rating of up to SIL 2 (SC 3) according to IEC/EN 61508. Therefore, it is widely used in oil, gas, chemical, and pharmaceutical industries where intrinsic safety, signal integrity, and long-term reliability are essential.
