Analog Input Signal
Ranges
−10 to 10 V
The −10- to 10-V range corresponds to the hexadecimal values F448 to 0BB8
(−3000 to 3000). The entire data range is F31C to 0CE4 (−3300 to 3300).
A negative voltage is expressed as a two’s complement.
0 to 10 V
The 0- to 10-V range corresponds to the hexadecimal values 0000 to 1770 (0
to 6000). The entire data range is FED4 to 189C (−300 to 6300). A negative
voltage is expressed as a two’s complement.
0 to 5 V
The 0- to 5-V range corresponds to the hexadecimal values 0000 to 1770 (0
to 6000). The entire data range is FED4 to 189C (−300 to 6300). A negative
voltage is expressed as a two’s complement.
