5V 30A 1 Channel Relay Module With Optocoupler Isolation

The 5V 30A 1-Channel Relay Module is a high-power switching module designed to control large electrical loads using low-power control signals. It features optocoupler isolation, which enhances safety and protects sensitive control circuits from high-voltage spikes and electrical noise.This is an easy-to-use 1-channel relay board that operates on 5V. Use it to control one 240V power appliance directly from microcontrollers or low-voltage circuits. Perfect for switching high-power 240V appliances - lights, fans, etc, and even high-power motors at lower voltages.

Key Features:

•  High Power Switching: Supports up to 30A at 250V AC, making it suitable for heavy-duty applications.
•  Optocoupler Isolation: Ensures electrical separation between the control circuit and the relay, reducing interference and protecting the microcontroller.
•  Wide Compatibility: Works with 5V DC control systems, including industrial controllers, sensors, and automation devices.
•  LED Indicators: Built-in LED indicators provide visual feedback for power and relay operation.
•  Durable and Reliable: Features a high-quality relay with long lifespan and strong mechanical contacts.
•  Protection Circuitry: Includes a flyback diode to protect against voltage spikes from the relay coil.
• The onboard jumper can set the module's high-level or low-level trigger input
