You can use an external power supply to power field devices.

Connect the positive lead of the external power supply to both

V terminals and the negative lead to both C terminals. Ensure that

the current through both V terminals can never exceed 2 A.

Install 2 A maximum, fast-acting fuses between the external power

supply and the V terminals. The wiring diagrams in this document

show fuses where appropriate.

Table 1 lists the terminal assignments for the signals associated

with each channel. The terminal assignments are the same for the

FP-TB-x terminal bases and the cFP-CB-x connector blocks.
