The 4 Channel 12V Relay Module With Optocoupler features isolated inputs that safeguard any vulnerable control circuitry.

Various microcontrollers, including Arduino, AVR, PIC, ARM and others, have the capability to control it.
By utilizing a high-voltage relay, the risk of overheating is eliminated compared to electromechanical relays which restrict current consumption based on their voltage rating.
The interface for the module is designed to streamline user interaction and enhance functionality.
As indicated by the relay voltage VCC, link the power supply for a favorable connection.
Connect the negative power to GND.
The high-level trigger signal triggers the end of the relay module effectively.
The relay module efficiently activates the high-level trigger to signal the end.
The high-level trigger signal triggers the relay module at the end.
The relay module efficiently sends a high-level trigger signal to the designated endpoint.
High level and low-level both refer to different degrees or levels of something. They represent the varying levels at which something can be measured or categorized.
The high-level trigger activates by receiving a positive voltage at the VCC connection of the anode and triggers the end of the relay when it is not in use.
Low-level trigger is when the voltage at the GND connection is utilized to activate the trigger and deactivate the relay once it reaches a low voltage of 0V or higher.
