Note
1. The input signal range can be set individually for each input.
2. Operation in ranges beyond the maximum input signals will damage the
Unit. Operate within the ranges listed above.
3. The accuracy is given for full scale. For example, an accuracy of
±
0.2%
means a maximum error of
±
8 (BCD).
The default setting is adjusted with the voltage input. When using the current
input, perform the offset and gain adjustment as required.
4. A/D conversion time is the time it takes for an analog signal to be stored in
memory as converted data after it has been input. It takes at least one cycle
before the converted data is read by the CPU Unit.
By executing an I/O refresh, the conversion time may be extended by an
additional 0.3 ms approximately.
