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.
