Precautions for replacement
When seventeen or more points
are used, use two QY50 modules.
Voltages exceeding 28.8VDC
cannot be applied.
Use caution on the used current of
the entire module.
As the common changes from
three commons to a common,
wiring with a different voltage for
each common is not possible.
