6 Electrical connection for 4-wire HART field devices with active current output (optional grounding not
shown)
1 Supply voltage for 4-wire HART field device
2 4-wire field device with active 4 to 20 mA-HART output
3 Electronic insert SWA50
4 PLC or transmitter with passive current input (optional), alternatively wire bridge between terminals OUT+
and OUT–
You must connect a PLC, a transmitter or a wire bridge to 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. If larger core cross-sections are required, we recommend remote
mounting.
FieldPort SWA50 without HART field device
With this connection version, you can preconfigure the FieldPort SWA50.
