4-1SectionSpecifications

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. D/A conversion time is

the time required for converting and outputting the PC data. It takes at least

one cycle for the data stored in the PC to be read by the Analog Output Unit.

By executing an I/O refresh, the conversion time may be extended by an

additional 0.3 ms approximately.

5. The default setting is for current output (load resistance: 250 Ω). When

using voltage output, or when using current output with a load resistance

other than 250 Ω, perform the offset and gain adjustment as required.
