🚀 Why It’s Ideal for Your Projects

• Safe isolation for control electronics – Built-in optocoupler separates the microcontroller from the relay’s power section, helping protect your board and sensitive parts from spikes or noise.

• Clear, simple integration – With a 5 V input logic level and a single control pin, it’s easy to wire and control from any standard GPIO.

• High load capability – The relay can switch common mains loads (10 A at 250 VAC) or comparable DC loads, making it versatile for lighting, motors, solenoids, and more.
