Output Signals
The XDIO connector handles output signals 0001 to 0008. Refer to 
 for output 
specifications. The locations of the signals on the connector are shown in 
. 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.
 shows two examples of different connections to the digital outputs on the 
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.
