Connect Power to the FP-3000
Insufficient powering is one of the main causes for problems observed with
the FP-3000. Calculate how much power your bank will require and
provide power accordingly.
Bank Power Requirements
As with any FieldPoint bank, the power requirements depend on the
network module, the I/O modules, and any devices being powered by the
analog or digital outputs.
The power supply connected to the network module provides power to
operate the entire bank of I/O modules via the backplane in the terminal
bases. It does NOT provide power for the output signals (such as an analog
outputs) unless you add external circuitry to make this the case.
I/O Power Requirements
For an output module, the Vsupply and Common terminals of the terminal
base must be wired and powered. Unless you add external circuitry, these
terminals are not electrically connected to the Vsupply and Common of the
backplane. They are used for power and referencing of the I/O signals only
(not the I/O module itself). For example, they are used with analog output,
digital output, pulse width modulator, or counter modules to provide power
for the outputs.
