0V to 10V DC input (14-bit mode only)
Conversion characteristic
(Note 1): In the analog input unit Ver.1.1 or earlier or the analog I/O unit, a digital conversion value equivalent to the
analog input of approx. 2 V is saved in the device (WX), for the channels to which no input is connected. The
analog input unit Ver.1.2 or later are equivalent to approx. 0V.
0V to 5V DC input
Conversion characteristic
(Note 1): In the analog input unit Ver.1.1 or earlier or the analog I/O unit, a digital conversion value equivalent to the
analog input of approx. 2 V is saved in the device (WX), for the channels to which no input is connected. The
analog input unit Ver.1.2 or later are equivalent to approx. 0V.
