Recommendations for Using the Extended-Depth Housing
Consider the following recommendations when deciding to use an
extended-depth housing on your Sequence of Events module. It is
recommended you use the 1756-TBE when:
• using >36 18AWG wires
• using >23 14AWG wires
Cabinet Size Considerations With the Extended-Depth Housing
When you use an extended-depth housing (1756-TBE), the module
depth is increased. The diagram below shows the difference, in
terms of depth, between a Sequence of Events module using a
standard-depth housing and one using an extended-depth housing.

IMPORTANT
The depth from front of the module to the back of
the chassis is as follows:
– standard-depth housing = 147.91mm (5.823in)
– extended-depth housing = 157.43mm (6.198in)
