Chapter 14 Remote I/O Communication Module AHRTU-PFBS
When the input/ output mode of the analog module is positive voltage or positive current,
the corresponding digital value is 0 ~32000; for example, if the modes are 0V~10V and
4mA~20mA, the corresponding digital values are both 0~32000.
When the input /output mode of the analog module is negative voltage or negative current,
the corresponding digital value is -32000~32000; for example, the modes are -10V~+10V,
and -20mA~20mA, the corresponding digital values are both -32000~32000.
 Pick "AH08DA-5B" and the related parameters are displayed as follows. The output modes
of CH0~ CH3 are all set to -10V~+10V. Double click the parameters in "Name" column. The
setting value can be revised directly if the mouse arrow becomes the "I" symbol. And select
hexadecimal or decimal as Display mode.
