Analog I/O Specifications
Note (1) The built-in analog input switch is used for toggling between voltage input
and current input. (The default setting at the time of shipping is for voltage
input.)
(2) Switching between 1/6,000 and 1/12,000 resolution is done in the PLC
Setup. The same resolution setting is used for all I/O words. It is not pos-
sible to set them individually.
(3) The total conversion time is the total of the conversion times for all the
points that are used. It would be 6 ms for 4 analog inputs and 2 analog
outputs.
(4) When the analog current output is within 0 to 20 mA, the accuracy cannot
be ensured if below 0.2 mA.
