Install the Local Expansion Module

This quick start uses a 1734-OB4E POINT I/O output module in a local expansion
module slot.

1. Make sure the DIN rail locking screw in the mounting base, for example, the 1734-TB

mounting base, is in the vertical position.

2. Align the tongue and groove slots

of the mounting base to the slots
on the right side of the controller
and push it back until it seats on
the DIN rail.

3. Use a small-bladed screwdriver to

rotate the DIN rail locking screw
to a horizontal position, locking
the mounting base in place.

4. Set the key position on the

mounting base before installing
the 1734-OB4E module.

This example shows position 1.

5. Make sure the output module’s key

position matches the position used
on the mounting base.
