    Overview Range of application The K-System devices from Pepperl+Fuchs are used for transmitting signals between field devices and a process control system/control system. The devices marked with "Ex" in the type designation are suitable for the connection of field devices used in potentially explosive atmospheres.
  • Page 6: Model Variants

    HART Loop Converter KFD2-HLC-(Ex)1.D(.**) Overview The HART system allows digital communication with HART field devices via cables for analogue 4 mA ... 20 mA field circuits. The HART Loop Converter KFD2-HLC-(Ex)1.D(.**) from the K-System HART (HLC) evaluates up to four HART variables (PV, SV, TV, QV).
  • Page 7: Safety Instructions

    If faults cannot be eliminated, the devices must be taken out of operation and protected from being placed in service again inadvertently. Devices must only be repaired directly by the manufacturer Pepperl+Fuchs. Tampering with or making changes to the devices is dangerous and therefore not permitted. They render the warranty void.
  • Page 8: Explosion Protection

    IP20 and must therefore be protected from undesirable ambient conditions (water, small foreign objects). Attention The devices of the K-system from Pepperl+Fuchs and thus also the HART Loop Converter KFD2-HLC-(Ex)1.D(.**) can be mounted on a 35 mm standard rail corresponding to DIN EN 50022. The devices must be snapped onto the rail vertically, and never slanted or tipped to the side.
  • Page 9: Connection

    HART Loop Converter KFD2-HLC-(Ex)1.D(.**) Installation and connection Dimensions of the KFD2-HLC-(Ex)1.D(.**) in mm Connection The detachable terminals of the KF-series considerably simplify the connection and the switch cabinet assembly. They make it possible to replace devices quickly and without error if a customer service becomes necessary.
