Output Signals
The XDIO connector handles output signals 0001 to 0008. Refer to Table 3-11 for output
specifications. The locations of the signals on the connector are shown in Table 3-12 on
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.
Figure 3-8 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.
