Chapter 10 Analog I/O Option Board (XBO-AH02A)
10.6.4 Gain Adjustment Function
You can adjust I/O gain of the analog I/O option board.
When selecting current input for analog input range, the digital output (4000) corresponding to analog
input max. value (20mA) is standard gain value. When selecting voltage input, the digital output
(4000) corresponding to analog input max. value (10V) is standard gain value.
(1) You can adjust input gain at I/O parameter
(2) I/O gain setting range = - 40 ~ 40
(3) Adjusting gain for each channel is available
(4) Example
When you set “Input gain” as -5, 4005 (=4000-(-5)) applies for gain.
(1) When you adjust the I/O gain, max. resolution changes, too.
