Wire Power to the FieldPoint System
A. Connect power supply leads to the V and C terminals of the network module. For up
to five I/O modules, use an 11–30 VDC, 15 W minimum power supply such as the
FP-PS-4. If you have more than five modules, you need a 20 W power supply. Refer
to the I/O module operating instructions for the power requirements of each module.
Refer to the
Specifications section of this document for instructions on calculating
the power requirement of the FieldPoint bank.
B. Connect power to the I/O modules that require external power for outputs (examples
include output, counter, relay, PWM, PG, and QUAD modules). It is generally best to
power each such module by connecting an external power supply to the V
SUP
and
COM terminals. Refer to the I/O module operating instructions for power
requirements, detailed wiring diagrams, and safe wiring practices.
