 13 Electrical connection for 4-wire HART field devices with active current output (optionally required
grounding not shown) – resistor at OUT terminals
1 Supply voltage (SELV, PELV or Class 2) for 4-wire HART field device
2 4-wire field device with active 4 to 20 mA-HART output
3 Electronic insert SWA50
4 Resistor 250 to 500 Ohm min. 250 mW between terminals OUT+ and OUT–
If you select the "direct mounting" version and the "4-wire HART field device with
active current output and PLC or transmitter" electrical connection version, you can
use core cross-sections of 0.75 mm² at maximum. The wires that you insert into the
shorter top housing section connect to the opposite terminals IN, and the wires that
you insert into the longer bottom housing section connect to the opposite terminals
OUT. If larger core cross-sections are required, we recommend remote mounting.
6.8 FieldPort SWA50 without HART field device
With this connection version, you can preconfigure the FieldPort SWA50.
