Analog Output Units
Section 7-3
■
0 to 20 mA
The hexadecimal values 0000 to 1770 (0 to 6000) correspond to an analog
current range of 0 to 20 mA. The entire output range is 0 to 21 mA.
■
4 to 20 mA
The hexadecimal values 0000 to 1770 (0 to 6000) correspond to an analog
current range of 4 to 20 mA. The entire output range is 3.2 to 20.8 mA.
