Photocoupler isolation between analog I/O terminals and internal circuits. No isolation
between analog I/O signals.
5 VDC: 100 mA max.; 24 VDC: 90 mA max.
Analog input data is digitally converted according to the input signal range as
shown below.
Note When the input exceeds the specified range, the A/D conversion data will be
fixed at either the lower limit or upper limit.
