5V Relay Module 1, 2, 4, 8 Channel with Optocoupler Isolation for Arduino & ESP32 – Price in Pakistan – Robochacha Official

Overview

The 5V Relay Module Series is the industry-standard solution for controlling high-voltage AC/DC appliances with low-power microcontrollers. Whether you are building a simple automated switch or a complex smart home hub, these modules provide the essential electrical isolation and switching power required for safe, reliable operation.

Key Benefits & Features

• High Switching Capacity: Safely manages loads up to 10A @ 250V AC or 30V DC, perfect for heavy-duty appliances.

• Advanced Opto-Isolation: Built-in optocouplers protect your sensitive Arduino or ESP32 from high-voltage back-EMF and electrical noise.

• Active-Low Triggering: Optimized for microcontrollers; the relay activates when the input signal is pulled to Ground (0V).

• Visual Status Feedback: Each channel features a dedicated LED that lights up when the relay is triggered.

• Flexible Power Design: Includes a JD-VCC jumper, allowing you to use an external power supply for the relay coils to prevent system brownouts.

Applications in Pakistan

• Smart Home Automation: Control 220V fans, LED lights, and water pumps via WiFi or Bluetooth.

• Engineering Student Projects (FYP): The go-to component for automation, robotics, and industrial prototypes.

• UPS & Battery Systems: Ideal for building custom automatic transfer switches (ATS) or load-shedding controllers.
