Mount the Optional Expansion Blocks
Mount the expansion block by connecting it to a previously-installed
CompactBlock LDX I/O base or expansion block.
Beginning with the base block, you can mount your expansion blocks
either horizontally or vertically:
•
horizontally (left to right) - add expansion blocks in a
end-to-end configuration
•
vertically (up or down) - add expansion blocks either up or
down in a back-to-back configuration. In this configuration, you
must use the optional 15cm ribbon cable (1790-15CMCBL) and
alternately position the blocks in a right-side up, upside-down
fashion.
You can mount your blocks on a panel or DIN rail as described in the
previous section.
Horizontal mounting
Vertical mounting
The longer expansion cable
(1790-15CMCBL) allows up to
7cm of space between blocks.
