About this product
A two-channel isolation module built around PC817 optocouplers, which transfer signals optically so that microcontrollers, PLCs, sensors and relays can be electrically separated. It is used for voltage level conversion and for reducing noise and ground loops between control circuits.

How do I wire the input and output sides?
The input side is an LED driven from the microcontroller through a current-limiting resistor. The output side is a phototransistor, so it needs a pull-up resistor and its own supply. Check the board for on-board resistors before adding external ones.
Are the two sides electrically connected?
No. The input and output sides share no direct electrical connection, so each side must be powered separately. Only the signal passes through the optical link.
