Chapter 4: Operation The following figure 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 24 V 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. NOTE: These are examples. Either method can be used, in any combination, on any channel. Also, an external customer-provided power supply could have been provided instead of the power provided on the XDIO connector.
