Function: KFD2-HLC-Ex1.D.2W

This isolated barrier is used for intrinsic safety applications. It is a HART loop converter that provides power to transmitters or can be connected to existing HART loops in parallel.

It is able to evaluate up to four HART variables (PV, SV, TV, QV). Of those four HART variables, the data contained in any three of them can be converted to three different 4 mA ... 20 mA current signals. These loop signals can be connected to display devices or analog inputs on the process control system/ control system.

In addition to the current outputs, two form C changeover relay contacts are available and can be programmed to operate at trip values from the HART variables.

The unit is easily programmed by the use of a keypad located on the front of the unit or with the PACTware™ configuration software.
