ibility
When 17 or more points are
used, use two QY50 modules.


As the number of points per
common is changed to 16, wiring
with a different voltage for each
common is not possible.

The QY50 does not detect fuse
 blown unless the external power
is supplied.
Voltage exceeding 28.8VDC is
not applicable.

The module configuration differs.
- Recalculate the current
consumption.
Wiring space is narrower.
