DRT1-AD04
–10- to 10-V Inputs
The –10- to 10-V range corresponds to the hexadecimal values 8BB8 to 0BB8
(–3000 to 3000). The most significant bit (bit 15) is set to 1 (ON) for negative
values and the AD conversion data is set to the absolute values; the rest of
the word indicates the absolute value. The entire data range is 8CE4 to 0CE4
(–3300 to 3300).
0- to 10-V Inputs
The 0- to 10-V range corresponds to the hexadecimal values 0000 to 1770 (0
to 6000). The most significant bit (bit 15) is set to 1 (ON) for negative values
and the AD conversion data is set to the absolute values; the rest of the word
indicates the absolute value. The entire data range is 812C to 189C (–300 to
6300).
0- to 5-V Inputs
The 0- to 5-V range corresponds to the hexadecimal values 0000 to 1770 (0
to 6000). The most significant bit (bit 15) is set to 1 (ON) for negative values
and the AD conversion data is set to the absolute values; the rest of the word
indicates the absolute value. The entire data range is 812C to 189C (–300 to
6300).
