Typical Digital Input Wiring
The following drawing shows three examples of different types of connections to the
digital inputs on the SIO. The methods are: negative common, positive common, and
independent (no common).
Example 1 inputs 1001 to 1004 shown with negative common.
Example 2 inputs 1005 to 1008 shown with positive common.
Example 3 inputs 1009 to 1012 shown with fully independent power supply (no
common).
Note: these are examples – in fact, any method can be used on any channel.
