2 ms/point (6 ms/all points)
Photocoupler isolation between analog I/O terminals and internal
circuits.
No isolation between analog I/O signals.
5 VDC: 83 mA max., 24 VDC: 110 mA max.
Analog I/O data is digitally converted according to the analog I/O signal range
as shown below.
When the input exceeds the specified range, the AD converted data will be
fixed at either the lower limit or upper limit.
