NOTE: The input current specifications are provided for reference;
voltage sources are typically used to drive the inputs.
NOTE: When the program task priorities are properly set, there is a 2 ms
maximum latency for fast inputs 1001 to 1004 when used with the V
+
INT.EVENT instruction.
In the following figure, example 1 shows inputs (1001 to 1004) with a negative common,
example 2 shows inputs (1005 to 1008) with a positive common, and example 3 shows
inputs (1009 to 1012) with an independent power supply (no common).
NOTE: These are examples. Either method can be used on any channel.
