Analog I/O Board Section 8-5
8-5-8 Specifications
Analog Inputs
Note 1. Separate input signal ranges can be set for each input.
2. The A/D conversion time is the time taken for an analog signal to be stored
in memory as digital data. At least one cycle is required to transfer the data
to the CPU Unit.
3. The overall precision is the precision with respect to full scale.
