(Note 1):The resolution and operation mode is switched by the mode switch.
(Note 2):When selecting the 14-bit mode, the range can be set for each channel separately by user programs. Also,
the ranges of -5 to 5 V DC and 0 to 10 V DC can be set by user programs only when selecting the 14-bit mode.
(Note 3):When selecting the 14-bit mode, the averaging method can be set for each channel separately by user
programs. For details of the averaging methods, refer to the chapter 5 "Analog Input Averaging Processing".
(Note 4): Installed in the unit of Ver.1.2 and after (only 12-bit mode).
(Note 5): In the case of the unit of Ver.1.2 and after; 20 mA for the unit of Ver.1.1 or older.
