Wiring Note:
⚫
The wiring principle of low-speed digital input IN (0-15) is shown in the figure above.
The external signal source can be an optocoupler, a key switch or a sensor, etc., all
can be connected as long as the requirements on output of electric level can be
achieved.
⚫
For the public end, please connect the "EGND" port on the power supply to the "COM"
terminal of the external input device. If the signal area power supply of the external
device and the power supply of the controller are in the same power supply system,
this connection also can be omitted.
3.2.2.
Basic Usage Method
(1)
Please follow the above wiring instructions to wiring correctly.
