Functional Safety HiD2022*, KFD2-STC5-(Ex)*, KFD2-STV5-(Ex)* Product Description KFD2-STC5-1.2O This signal conditioner provides the galvanic isolation between field circuits and control circuits. The device supplies 2-wire and 3-wire SMART transmitters, and can also be used with 2-wire SMART current sources. It transfers the analog input signal to the control side as two isolated output signals. Digital signals may be superimposed on the input signal on the field side or on the control side and are transferred bi-directionally.

As noted in DIN EN 61508-2:2011 note N3, appropriate measures taken by the manufacturer and plant operator can extend the useful lifetime. Our experience has shown that the useful lifetime of a Pepperl+Fuchs product can be higher if the ambient conditions support a long life time, for example if the ambient temperature is significantly below 60 °C.
