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.
