ENQUIRE NOWProduct Overview
The Pepperl+Fuchs KCD2-STC-Ex1 is a 1-channel isolated barrier SMART transmitter power supply in the compact 12.5 mm K-System housing. It powers 2-wire SMART transmitters, or accepts 2-wire current sources, in the hazardous area and provides a 4 … 20 mA or 1 … 5 V output to the control system.
The output can operate in source or sink mode, HART communication is supported, and the device is suitable for applications up to SIL 2 (SC 3) to IEC/EN 61508. Supplied at 24 V DC via the Power Rail, it carries ATEX, IECEx, FM and UL approvals and allows high packing density in control cabinets.
