Output Signals
The XDIO connector handles output signals 0001 to 0008. Refer to
specifications. The locations of the signals on the connector are shown in
page
63. The XDIO connector provides separate positive and negative connections for
each channel (no internal common connections). This allows the choice of wiring for
current-sourcing or current-sinking modes.

XDIO connector. The examples are negative common and positive common using the
internal 24V and ground connections.
Example 1: outputs 0001 to 0004 are shown with positive common.
Example 2: outputs 0005 to 0008 are shown with negative common.
