ENQUIRE NOWProduct Overview
The Pepperl+Fuchs KFD2-STC5-Ex2 is a 2-channel isolated barrier SMART transmitter power supply. It powers 2-wire and 3-wire SMART transmitters, and accepts 2-wire SMART current sources, in the hazardous area, repeating each 4 … 20 mA signal to the safe area as a current sink or current source output.
HART communication is transferred bi-directionally and terminals with test points simplify loop checks. Supplied at 24 V DC via the Power Rail, the module is ATEX and IECEx certified, suitable for applications up to SIL 2 (SC 3) to IEC/EN 61508, and can also be installed in Zone 2.
