*1
12VDC cannot be used.
*1
12VDC cannot be used.
*2
Input resistance is greater.
The name is different, but the
specificaton is equal.
Set the input response time of the
parameter to 5ms before use.
Set the input response time of the
parameter to 1ms before use.
Precautions for replacement
The maximum load current per
point is smaller. Use caution on
selecting the load to use.
The inrush current value differs.
Use caution on selecting the load
to use.
The response times differ.
Voltages exceeding 28.8VDC
cannot be applied.
