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.

Model variants
The following variants of the HART Loop Converter are available:
KFD2-HLC-**1.D.**

The HART Loop Converter
KFD2-HLC-(Ex)1.D(.**) from the K-System
(HLC) evaluates up to four HART variables
(PV, SV, TV, QV). The information can be
converted to three different 4 mA ... 20-mA
current signals and conveyed to display
devices or analogue inputs on the process
control system/control system, for example.
In addition, two or four configurable trip values
from the HART variables can be monitored via
the relay outputs on the KFD2-HLC-
(Ex)1.D.2W or KFD2-HLC-(Ex)1.D.4S.
.2W = with 2 change-over contacts
.4S = with 4 normally open contacts
no identification letters = without relay
Ex = for connection of field devices in areas exposed to danger of
explosion
without identifier letters = for connection of field devices in the
secure area
