Jumper J1 is disabled when inputting 0V ~ 10V analog voltages
the two lower pins of J1 are short circuited when inputting 0mA ~ 10mA signals,
and the two upper pins of J1 are short circuited when 0 ~ 24V signals are inputed.
(The resistance of the potentiometer shall be higher than 3K, and its power rate shall be more than
1/4W. It is recommended to adopt the potentiometer with resistance ranging from 5K to 10K).
Note:
In the above three schemes of analog signal input, all the signals will be regulated through the
internal circuit. Therefore, all the input signals are converted into voltage signals of 0V ~ 10V.
