*1 Consider the characteristics of the triac and observe the necessary precautions by referring to Section 3.3 (3) before
replacing the modules.
*2 Install a fuse for each external terminal point to prevent the burnout of the external devices and modules during load shorts.
In addition, when a fuse blown indication is necessary, configure an external circuit.

Precautions for replacement
When seventeen or more points
are used, use two QY22 modules.
The frequency will be low. Check
the specifications of external
devices.
The minimum load current is
greater. Use caution on selecting
the load to use.
As the common changes from
three commons to a common,
wiring with a different voltage for
each common is not possible.
