How to connect the optocoupler voltage conversion module
Simply supply the module with 5V DC and GND through the terminals below. Additionally, connect the 5V active low input pins (Optocoupler circuit inputs) to your Arduino ports to be able to control the relays. There is an available jumper that can provide isolation for the input. An optocoupler (also called an opto-isolator or photocoupler) is a component that transfers an electrical signal between two isolated circuits using light. Because the signal crosses as light —. This tutorial gives an introduction to the HY-M154 / 817 optocoupler module. In my examples, I use the Raspberry Pi, which uses 3. 3V DC signals, and a PLC (Programmable Logic Controller) operating at higher voltages (often 24V DC). These 5V multi-channel relay modules are convenient devices for controlling an external load using low power/low voltage devices such as an Arduino.
