*** Caution ***

If the jumper is set, the GND of the input and output signals are connected.

If you need fully isolated input and output signals, you must remove the jumper.

✍ Optocoupler module frequent found on well design equipment control panel or PLC control circuit to ensure I/O isolation for MCUs (Micro Controller Units), prevent noise suppression in switching circuits and to achieve signal transmission between circuits of different potentials and impedances.

▼ Features:
Jumper cap can set output port to high potential or pull down to GND
Using 817 optocoupler to achieve the control signal and the control signal isolation
You can directly use the microcontroller or other device's IO port to achieve voltage isolation control
