1 The analog output range is set commonly for CH1 to CH2.
2 The conversion speed refers to the speed between the times when a digital value is written to the
A1S66ADA and when an analog output which corresponds to the aforementioned value begins to be
outputted.
3 The analog input range is set commonly for CH3 to CH6.
4 The conversion speed refers to the speed while a change in an analog input is converted to a digital
output. (Excluding the sequence scan)
5 Inputs and outputs are assigned to the same number. Therefore, the I/O occupied points are 64.
POINT
When utilizing the peripheral device to assign the I/O numbers, set it as a 64-point
output module.
