Wiring the [c]FP-AI-112
The FP-TB-x terminal base has connections for each of the
16 input channels and for an optional external power supply to
power field devices. The cFP-CB-x connector block provides the
same connections. Each channel has one input terminal (V

) for
voltage input. All 16 inputs are referenced to the COM terminals,
which are internally connected to each other and to the C terminals.
The channels share eight V
SUP
terminals, all of which are internally
connected to each other and to the V terminals.
