SAFETY BARRIER AMPLIFIER KFD2-STC4-EX1.2O PEPPERL+FUCHS
AMPLIFIER FOR SAFETY BARRIERS KFD2-STC4-EX1.2O PEPPERL+FUCHS PART 231389
1-channel insulated barrier
24 V DC power supply (power rail)
Input for 2-wire and 3-wire SMART transmitters and 2-wire SMART power supplies
Signal divider (1 input and 2 outputs)
Double output 0/4 mA ... 20 mA
Terminal blocks with test sockets
Up to SIL 3 according to IEC 61508
This isolated barrier is used for security applications
intrinsic.
Device powers 2-wire and 3-wire SMART transmitters
in hazardous environments, and can also be used with
2-wire SMART power supplies.
Transfers analog input signal to secure environment
as two isolated current values.
Digital signals can be superimposed on the
entry into the hazardous or safe environment and are transferred from
Bidirectional shape.
If the HART communication resistance of the loop is
too low, the internal resistance of
250 ? between terminals 8, 9 and 11, 12.
Device terminals integrate test sockets
for the connection of HART communicators.
Application
The device supports the following protocols
SMART:
•HART
• BRAIN
•Foxboro
