Pepperl+Fuchs KFD2-STC4-Ex1 SMART Transmitter Power Supply
This Pepperl+Fuchs KFD2-STC4-Ex1 SMART Transmitter Power Supply / Isolated Barrier is used for intrinsically safe applications. The device supplies 2-wire and 3-wire SMART transmitters in a hazardous area, and can also be used with 2-wire SMART current sources. Durable, this isolation barrier transfers the analog input signal to the safe area as an isolated current value.
- 1-channel isolated barrier
- 24 V DC supply (Power Rail)
- Input 2-wire and 3-wire SMART transmitters and 2-wire SMART current sources
- Output 0/4 mA … 20 mA
- Terminals with test points
- Up to SIL2 acc. to IEC 61508
Digital signals may be superimposed on the input signal in the hazardous or safe area and are transferred bi-directionally. If the HART communication resistance in the loop is too low, the internal resistance of 250 Ω between terminals 8 and 9 can be used. Test sockets for the connection of HART communicators are integrated into the terminals of the device.
