Function
This isolated barrier KFD2-SCD2-Ex2.LK is used for intrinsic safety applications. It drives SMART I/P converters, electrical valves, and
positioners in hazardous areas. Digital signals are superimposed on the analog values at the field or control side and are transferred bi-directionally.
Current transferred across the DC/DC converter is repeated at terminals 1, 2 and 4, 5.
An open and shorted field circuit presents a high input impedance to the control side to allow line fault detection by control system. Pepperl+Fuchs isolated barrier KFD2-SCD2-Ex2.LK
If the loop resistance for the digital communication is too low, an internal resistor of 250 Ω between terminals 8, 9 and 11, 12 is available, which may be used as the HART communication resistor. Pepperl+Fuchs isolated barrier KFD2-SCD2-Ex2.LK
Sockets for the connection of a HART communicator are integrated into the terminals of the device.
A unique collective error messaging feature is available when used with the Power Rail system.
