When 9 or more points are used,
use two QY68A modules.

Wiring of the terminal block
needs to be changed because all
terminals become independent.

Wiring change is required.

When two QY68A modules are
used, the current consumption is
increased. Review the current
capacity.
Wiring space is narrower.
