Why Choose This?
- True 30A high-current switching: Handle heavy loads like water heaters, motors, industrial pumps, and high-wattage appliances that standard 10A relays cannot manage
- Optocoupler isolation: Protects your microcontroller from high-voltage spikes and electrical noise on the load side, ensuring safe and reliable operation
- Heavy-duty screw terminals: Thick gauge screw terminals rated for high-current wiring - secure connections that won't loosen under load
- Simple 3-pin interface: Connect VCC, GND, and a single signal pin - active-low trigger makes it compatible with virtually any 5V microcontroller
- Onboard LED indicator: Instantly see relay state at a glance for easy debugging and monitoring
- 100% authentic from trusted suppliers: Sourced from authorized distributors with quality verification
- 1-5 day shipping, 7-8 day delivery from Bengaluru warehouse: Fast delivery across India, same-day within Bengaluru
- Expert technical support included: Get help with wiring, code, and integration from our engineering team
Project Ideas
- Home Automation (High-Power): Control water heaters, geysers, air conditioners, room heaters, and heavy kitchen appliances remotely via smartphone or voice assistant using ESP32/ESP8266 with Blynk or Home Assistant
- Industrial Motor Control: Switch high-current single-phase motors, compressors, and industrial fans on/off with microcontroller logic and safety interlocks
- Solar Power Management: Build an automatic transfer switch (ATS) that toggles between solar inverter and mains power based on voltage sensing
- Water Pump Automation: Create a smart irrigation or tank-filling system using water level sensors and Arduino to automatically start/stop a submersible or centrifugal pump
- EV Charging Station Controller: Manage high-current charging circuits for electric vehicles or e-bikes with timer-based or app-controlled switching
- 3D Printer & CNC Heated Bed Control: Safely switch high-current heated beds or spindle motors with PID-controlled microcontroller output
- Generator Auto-Start System: Detect mains power failure and automatically trigger a generator starter circuit with appropriate delay logic
- Aquarium & Greenhouse Automation: Control high-wattage heaters, UV sterilizers, and circulation pumps on scheduled or sensor-triggered cycles
- Learning & Education: Ideal for engineering students learning about relay interfacing, optocoupler isolation, high-voltage safety, and embedded systems design
