2 Channel 24V Relay Module with Optocoupler
This 2-Channel 24V Relay Module with Optocoupler meets safety standards with isolation grooves between the control and load areas, providing optical coupling isolation.
The module’s 2-channel relay triggering is reliable and stable, thanks to its double FR-4 circuit board design and high-end SMT manufacturing process. It includes power and relay operation indicators, and the relay terminals (C, NC, NO) are accessible via screw terminals, simplifying wiring.
The module's inputs are isolated to safeguard sensitive control circuits, making it compatible with a variety of microcontrollers such as Arduino, AVR, PIC, and ARM.
Using high-voltage relays helps prevent overheating, as electromechanical relays manage current consumption according to their voltage rating.

The positive (according to the relay voltage VCC: connect power supply)
GND: connect power negative
IN1: relay module (effective) high-level trigger signal trigger end
IN2: relay module (effective) high-level trigger signal trigger end
- High-level trigger refers to using the anode voltage at the VCC connection way of a trigger and triggers the end when the trigger side has a positive voltage or to trigger voltage when the relay is off.
- Low-level trigger refers to using the negative voltage at the GND connection way of a trigger and triggers the end when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.
Features :
- Equipped with high-current relay 10A@250VAC / 10A@30VDC
- It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc
- High-quality screw terminals (Terminal Block) provided (C, NC, NO) for quick and easy connection
- Freewheeling diode to protect your microcontroller
