■
4 to 20 mA
When the resolution is 1/6,000, 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.
When the resolution is 1/12,000, the hexadecimal values 0000 to 2EE0 (0 to
12000) correspond to an analog voltage range of 4 to 20 mA.
The entire output range is 3.2 to 20.8 mA.
