Function
KFD2-STV4-2-1
This signal conditioner provides the isolation for nonintrinsically safe applications.
LED green:
Power supply
PWR
The device supplies 2-wire SMART transmitters.
It transfers the analog input signal as an isolated voltage
value.

13 14 15
Digital signals may be superimposed on the input signal 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, 9
and 11, 12 can be used.
Removable terminals
green
Test sockets for the connection of HART communicators are
integrated into the terminals of the device.
Application
The device supports the following SMART protocols:
• HART
• BRAIN
• Foxboro

Accessories
Power feed module KFD2-EB2
The power feed module is used to supply the devices with 24 V DC via the Power Rail. The fuse-protected power feed module
can supply up to 150 individual devices depending on the power consumption of the devices. Collective error messages received
from the Power Rail activate a galvanically-isolated mechanical contact.
Power Rail UPR-03
The Power Rail UPR-03 is a complete unit consisting of the electrical insert and an aluminium profile rail 35 mm x 15 mm. To
make electrical contact, the devices are simply engaged.
Profile Rail K-DUCT with Power Rail
The profile rail K-DUCT is an aluminum profile rail with Power Rail insert and two integral cable ducts for system and field cables.
Due to this assembly no additional cable guides are necessary.
