Wiring the [c]FP-AO-200
The FP-TB-x terminal base provides connections for the eight
output channels of the FP-AO-200. The cFP-CB-x connector block
provides the same connections for the cFP-AO-200.
Table 1 lists the terminal assignments for the signals associated
with each channel.

Each channel has an output terminal, I
COM; and a supply terminal, V
the channels are connected internally to each other and to the
C terminals, and the V
and to the V terminals. Refer to the sections that follow for detailed
wiring instructions.
Sourcing Current to a Load
The [c]FP-AO-200 sources current from an external loop supply to
a load. The [c]FP-AO-200 can operate with an external loop supply
from 5 to 24 VDC. The voltage from the external supply
determines the maximum load impedance that the [c]FP-AO-200
can drive. With a 24 VDC loop supply, each output can drive up to
1 kΩ of load impedance. With a 5 VDC loop supply, each output
can only drive up to 100 Ω. The [c]FP-AO-200 detects and reports
error conditions due to excessive loads or insufficient loop
supplies. For more information, refer to the
section.
