2 Channel 5V Relay Module with Optocoupler Isolation for Arduino & ESP32 in Pakistan

Makers choose the 2 Channel 5V Relay Module to control high-power appliances safely. Specifically, this board allows a low-voltage microcontroller (like an Arduino or ESP32) to switch heavy AC loads. Therefore, you can easily turn on lights, fans, or water pumps using simple code. Furthermore, the manufacturer includes built-in optocouplers on the board. As a result, these optical isolators completely protect your sensitive electronics from dangerous voltage spikes.Additionally, this module offers independent control over two separate circuits. Consequently, you can manage a heater and a cooling fan simultaneously from a single Arduino. Moreover, the board uses sturdy screw terminals for the high-voltage connections. Because of this, you get a secure and reliable physical connection for your heavy-duty wires.Key Features Optocoupler Isolation: The board includes dedicated optical isolators. Consequently, high-voltage surges cannot travel back and destroy your microcontroller.Dual Control: You can control two independent devices at the exact same time. As a result, it works perfectly for multi-room lighting projects.High Current Capacity: Each relay easily handles up to 10A at 250V AC or 30V DC. Therefore, you can confidently power heavy household appliances.Active Low Trigger: You activate the relays by sending a low (GND) signal. Importantly, this logic makes it seamlessly compatible with both 3.3V and 5V microcontrollers.LED Indicators: The board features red and green indicator LEDs. Specifically, these lights show you the power status and the activation state of each relay at a glance.Technical Specifications FeatureSpecificationOperating Voltage5V DCNumber of Channels2 Independent RelaysMaximum Load (AC)10A @ 250V ACMaximum Load (DC)10A @ 30V DCTrigger LogicActive Low (0V to trigger)Isolation TypeOptocoupler (Photocoupler)Dimensions50mm x 38mm x 17mm
