12VDC cannot be used.
*3
Input resistance is greater.
The name is different, but the
specificaton is equal.
Input response time of the
parameter must be used at the
initial value (10ms).
Precautions for replacement
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.
