Output Current 2 Channels
Count vs Output Current
The graph below shows the relationship between the output data that is
provided to the module from the backplane, and the actual output current. The
range spans between 4mA and 20mA.

The following equation can be used to calculate specific output currents:
The count value must be a multiple of 8. If the module receives a count value
that is not a multiple of 8, it rounds the value down to the closest multiple of 8.
