Select A or B. For external power source . . . Select C or D.
For internal power source
Note
Review the check items below before selecting your settings.
You must use the same power source for control output signal and DC
isolated input signal.
If you select COM1 for COMMON and use internal power source output,
comparator signals will not be opto-isolated.
If you select COM2 for COMMON and choose to use internal power source
output, comparator signals will not be opto-isolated.
