4 Channel 5V Relay Module with Optocoupler Isolation for Arduino, Raspberry Pi & ESP32 in Pakistan

Makers choose the 4 Channel 5V Relay Module when they need to manage multiple high-power appliances from a single board. Specifically, this module enables a low-voltage microcontroller to switch four separate AC or DC loads. Consequently, you can automate your entire rooms lighting or control several water pumps with ease. Furthermore, the board includes built-in optocouplers for every channel. As a result, these components physically isolate your microcontroller from high-voltage interference and spikes.

Additionally, this 4-channel version provides a centralized solution for complex projects. Therefore, you save significant space compared to using four individual relay modules. Moreover, the board features high-quality screw terminals for all output connections. Because of this, you can securely attach thick power cables without worrying about loose wires or short circuits.

Key Features

• Quad-Channel Control: You can switch four independent devices simultaneously. Specifically, this makes it ideal for DIY smart home hubs.

• Optocoupler Isolation: The board includes dedicated optical isolators for each relay. Therefore, your Arduino or Raspberry Pi remains perfectly safe from electrical noise.

• Heavy-Duty Switching: Each of the four relays handles up to 10A at 250V AC. Consequently, you can drive powerful motors and household electronics confidently.

• Standard 5V Logic: The module works seamlessly with 5V signals. Furthermore, it supports 3.3V logic from boards like the ESP32 or Raspberry Pi Pico.

• Clear Visual Feedback: Every channel has its own status LED. As a result, you can visually confirm which relays are active at any given moment.
