Types of I/O cards on functional Modules
Input/Output (I/O) Cards connect the Functional Modules to external systems
and networks. The I/O Cards are housed behind the Backplane, opposite the
Functional Modules.
The I/O Cards, which are small and simple, are installed via the rear panel of
the MGC+. A connector at the rear of each I/O card connects the card to the
Backplane.
The following I/O cards can be installed on functional cards of the MCU:
