Description:

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 an 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 following section.

Panel Mounting

1. Place the block against the panel where you want to mount it.

2. Gently pull and position the expansion cover to the left.

3. Place a center punch, nail or similar device through the mounting holes in the 

block and make two marks on the panel (lower left and upper right corners of the 

module). 

4. Remove the block and drill two holes in the panel to accommodate each of the 

mounting screws.
