2.2. The Plug-In Output Board
The MultiFlex CUB has an output sub-board
that plugs to the top of the baseboard. Typically,
these boards are shipped with the output board
pre-installed on the board using stand-offs, so no
additional hardware setup should be necessary.
The additional board makes the MultiFlex
CUB boards considerably taller than the Multi-
Flex 16 and other CPC I/O boards. If you will be
mounting these boards in an enclosure, the board
will need at least 2.5” of clearance between the
baseboard and the panel door.
2.3. Powering the MultiFlex
CUB Board
CPC supplies a wide variety of 24VAC trans-
formers with varying sizes and either with or
without center taps.
Table 2-1
shows the trans-
former sizes and whether they are center-tapped
or non-center-tapped.

WARNING: All models of MultiFlex require a
24VAC Class 2 input power source. The Multi-
Flex CUB-II requires the power source to be
non-center-tapped. Refer to Section 2.3.1.,
Choosing Transformer Sizes for center tap usage.
