Description
Here is an example to explain the precision of BD board.
Example: AD channel precision is 14-bit, analog input range is 0-5V or 0-10V. The transformed digital range
is 0~16383.
If the analog range is 0~5V, when the input voltage is 0V, the digital value is 0V, when the input
voltage is 5V, the digital value is 16383. If the analog range is 0~10V, when the input voltage is 0V, the digital
value is 0V, when the input voltage is 10V, the digital value is 16383. This is the relationship between input
signal and transformed digital value.
For example, the pressure sensor signal is 0-10V, the sensor range is 0-15Mpa, the present pressure value will
be shown on the HMI screen.
External installation and wiring
Open the BD cover of ZG3 controller, insert the BD board into the pins, then close the cover.
