Precautions for replacement
*1
12VDC cannot be used.
*2
Rated input current is smaller.
*1
12VDC cannot be used.
*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
Voltages exceeding 28.8 VDC
cannot be applied.
Voltages exceeding 28.8 VDC
cannot be applied.
As the common changes from two
commons to a common, wiring with
a different voltage for each
common is not possible.
