HART Loop Converter KFD2-HLC-(Ex)1.D(.**)
Installation and connection
5.2.1 Connection input (field circuit)
The intrinsically safe field circuit is connected to the blue terminals 1 to 6 on the KFD2-HLC-Ex1.D(.**).
This may be conducted using DIN EN 60079-14-compliant leads into the hazardous area.
You can connect the following three operating modes:
1. any separately powered HART loop with a transmitter or positioner in a parallel circuit (as with
HART handheld terminals, terminals 2 and 3)
2. an active HART-compatible mA source, e. g. a separately powered HART transmitter (terminals 2
and 3, bridge between terminals 5 and 6)
3. a 2-wire HART transmitter (HART transmitter with analogue 4 mA ... 20 mA output signal) powered
by the HLC (terminals 1 and 3, bridge between terminals 4 and 5)
