Voltages from 0…10 VDC
The decimal values for the current values from 0…10 VDC can be calculated by means of the follow-
ing equation:
decimal value = 3276.7 /1V × voltage value
The decimal value can easily be converted into a hexadecimal value, because all numbers belong to
the positive range of the two’s complement.
Voltage values in the range of -10 … 10 V DC
The decimal values for the current values from -10…10 VDC can be calculated by means of the fol-
lowing equation:
For positive values 0 …10 VDC:
decimal value = 3276.7 /1V × voltage value
The value range:
0 V…10 V
is displayed as follows:
0000
hex
…7FFF
hex
(decimal: 0…32767)
For negative voltage values -10 …0 VDC:
decimal value = 3276.8 /1V × voltage value
The value range:
-10 V…-3.052 10
-4
V
is displayed as follows:
8000
hex
…FFFF
hex
(decimal:-32768…-1)
