Connecting To GPI / GPO Phoenix Terminal Connectors
Figure 2-2 shows connections to the card Phoenix™ terminal block GPI and
GPO connectors. These terminal blocks use a removable screw terminal
binding post block which allows easier access to the screw terminals.
Note: It is preferable to wire connections to Phoenix plugs oriented as shown in
Figure 2-2
rather than assessing polarity on rear module connectors. Note
that the orientation of rear module connectors is not necessarily consistent
within a rear module, or between different rear modules. If wiring is first con-
nected to Phoenix plug oriented as shown here, the electrical orientation will
be correct regardless of rear module connector orientation.
