AEDIKO 4pcs DC 24V Relay Module - 1 Channel With Optocoupler Isolation, High/Low Level Trigger, 10A Load

Need a reliable relay module for your electronics project? This 4-pack from AEDIKO is a solid choice. Each module runs on 24V DC and can handle up to 10A loads — that's AC 250V or DC 30V. It's got optocoupler isolation to protect your microcontroller, a jumper to choose between high or low-level triggering, and screw terminals that make wiring a breeze. Even if the control line gets disconnected, the relay won't accidentally activate. Works great with Arduino, Raspberry Pi, PLCs, and other control systems. Whether you're automating lights, motors, or appliances, these little boards are tough, stable, and super handy to have around.
