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.
Outputs 0001 to 0004 are shown with a positive common. Outputs 0005 to 0008 are shown
with a 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.
