Kingfisher Plus+ Hardware Manual
Point-to-point Wiring Configuration (Utilising Analogue Input)
Note: the resistor value can be from 50 to 500 Ohm. The 24 V field power output of the
DC
Analogue Input Module is used to power the current loop in this case. A generic power
supply can be used instead.
Multi-drop Wiring Configuration
Note: the resistor value can be from 50 to 500 Ohm. The more HART devices connected, the
closer the resistor value needs to be to 50 Ohm.
When using multiple HART networks on a single RTU, be sure to isolate the 24 V supplies.
