Wiring Note:
⚫
The wiring principle of digital inputs 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 expansion module are in the same power supply
system, this connection also can be omitted.
