The 5V Dual Channel Relay Module with Optocoupler is an essential interface board designed to let microcontrollers, Arduino boards, and IoT controllers switch heavy AC or DC loads safely. 5V DC logic level · Up to 10A at 250V AC or 10A at 30V DC per channel.
The 5V Dual Channel Relay Module with Optocoupler is an essential interface board designed to let microcontrollers, Arduino boards, and IoT controllers switch heavy AC or DC loads safely. Each of the 2 onboard relays is equipped with high-current switching contacts capable of handling up to 10A at 250V AC or 30V DC.
Featuring built-in optocoupler isolation, this module protects sensitive control circuitry from voltage spikes, electrical noise, and back-EMF. It includes trigger selection jumpers allowing high-level or low-level triggering, optical isolation for each channel, and working indicator LEDs to easily monitor relay status during prototyping and deployment.
