SYNC OUTPUTS (1 to 4)
These signals are optically isolated and require the user to provide a high voltage level (USER
VCC) and signal common (USER GROUND). USER VCC can be from 5V to 24V. ICC is a function of
USER VCC and load resistor R. An example of the functional circuit is indicated in the following
diagram.
