The Excitation Module can supply 12 VDC at up to 100 mA for external sensors or encoders.
This excitation is isolated from the counter internal logic supply.
When using sensors or encoders that do not have a signal return or imply a signal return that
is in common with the supply voltage, a common attachment that ties the excitation supply to
the logic input common may be required.
Examples of this appear in figures 8, 8a, 11 and 12.
