Precautions for replacement
When seventeen or more points
are used, use two QX40 modules.
*1
12VDC cannot be used.
*2
Rated input current is smaller.
12VDC cannot be used.*1
*1
12VDC cannot be used.
*1
12VDC cannot be used.
*2
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
When seventeen or more points
are used, use two QY10s.
Although the insulation methods
differ, the performance of the
insulation is same.
