Precautions for replacement
When seventeen or more points
are used, use two QY80s.
The maximum load current per
point is smaller. Use caution on
selecting the load to use.
The inrush current value differs.
Use caution on selecting the load
to use.
The response times differ.
Voltages exceeding 28.8VDC
cannot be applied.
The QY80 has the fuse instead of
overheat and short circuit
protection function.

As the common changes from
three commons to a common,
wiring with a different voltage for
each common is not possible.
Precautions for replacement
Review current capacity since
current consumption is increased.
