You can use an external power supply to power field devices.
Connect the positive lead of the external power supply to both
Vterminals and the negative lead to both C terminals. Ensure that
the current through both V terminals can never exceed2 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.
Table1 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.
