Wiring the [c]FP-AI-110
The FP-TB-x terminal base has connections for each of the eight
input channels and for an external power supply to power field
devices. The cFP-CB-x connector block provides the same
connections. Each channel has separate input terminals for voltage
(VIN) and current (IIN) input. Voltage and current inputs are
referenced to the COM terminals, which are internally connected
to each other and to the C terminals. All eight VSUP terminals are
internally connected to each other and tothe V terminals.
You can use a 10–30 VDC external supply to power field devices.
Connect the external power supply to multiple V and VSUP
terminals so that the maximum current through any V terminal
