Duplication and Expansion
Planning and Installation Manual 125
Partial Chassis Output Duplication
As previously described (starting on page 43), the PE-33016 Port
Expander can be used to provide dual outputs in blocks of 16 outputs,
while the PE-33008 Port Expander can be used to provide quad outputs
in blocks of 16 outputs.
For example, Figure 62 shows outputs 1-16 with dual outputs and the
remainder with single outputs.
Figure 62.
In this example:
• For SO-33110/33011 and HO-33110/33011 output boards,
the gain for outputs 1-16 would be boosted by closing the
rear-panel Input Expand DIP switch and verifying that the
on-board jumper for that set of outputs is in the “Expand
Enable” position. The location of the boost jumper on these
output boards is shown on page 128. The gain for outputs
17-256 must be held at unity by setting the on-board jumpers
for that set of outputs to the “Force Normal” position; this
overrides the rear-panel DIP switch setting for those out-
puts.
• For HO-33120/33121 output boards, the gain for outputs 1-
16 would be boosted by closing the rear-panel Input Expand
DIP switch and verifying that the on-board DIP switch for
those outputs is closed. The location of the DIP switches for
these boards is shown on page 129. The gain for outputs 17-
256 must be held at unity by opening the on-board DIP
switches for that set of outputs; this will override the rear-
panel DIP switch setting for those outputs.
