Figure 41: Powering FX16X Rev. A Controller and I/Os
In the FX16X Rev. A controller, the power supply is isolated from the
Central Processing Unit (CPU) circuits and is connected internally to
the Analog Output (AO) and Digital Input (DI) power supply. External
power supply connections for the AO and Digital Output (DO) circuits
are not required. Run the power supply cable to the controller (Figure
41), adding an external fuse (2 ampere) to protect against incorrect
wiring.
IMPORTANT: In the FX16X Rev. A controller, the Power Com, AO Com, and
DI Com terminals are electrically connected.
