YDLIDAR TG15 ToF Series Distance Sensor Rangefinder 15M 360Β° UART βΉ39,999.00 Microcontrollers like the Arduino or ESP32 are great for logic, but they can’t directly turn on a 220V light bulb or a heavy DC motor. The 8 Channel Relay Board - 5V is the bridge between your code and the real world. It allows you to control up to eight independent high-power circuits using simple 5V logic signals. Whether you are building a smart home system, an automated garden, or an industrial sequencer, this board provides the muscle your project needs.
Switching high voltage is dangerous for your sensitive electronics. That’s why our 8-channel boards are Probots Lab Verified, featuring full opto-isolation. This means there is no direct electrical connection between your microcontroller and the high-voltage side, preventing back-EMF and spikes from damaging your processor. To ensure reliability, we’ve made this Probots Power-Safe by using heavy-duty copper traces and high-quality screw terminals that won't strip during installation. Your board is shipped in Probots Secure-Transit anti-static packaging to ensure it arrives in perfect condition.
Channels: 8 Independent Relays.
Control Signal: 5V DC (Active Low).
Switching Capacity: 10A @ 250VAC / 10A @ 30VDC.
Isolation: Opto-isolated.
Indication: Individual LED status indicators for each channel.
Power Requirement: 5V DC for VCC.
Dimensions: 138mm x 56mm x 19mm.
Terminals: High-quality Screw Terminals (NO, COM, NC).
Smart Home Automation: Control 8 different lights or appliances via Wi-Fi (using an ESP32).
Industrial PLC Replacement: Creating custom logic controllers for machinery.
Automated Greenhouses: Managing water pumps, fans, and grow lights on a schedule.
Audio/Visual Switching: Routing high-power signals in theatre or stage setups.
Past Projects (Prerequisites): If you've controlled a single LED or a single relay module, you've mastered the basics.
Feature Upgrade: This board unlocks Multi-Load Synchronised Control. You can now program complex "scenes" (e.g., turn off the lights, lock the door, and start the fan with one command).
Effort/Requirements: Beginner-Friendly. Requires only basic digital output programming and standard jumper wires.
⚠️ Safety Warning: You are dealing with Mains Voltage (220V). Always disconnect the power before wiring and ensure all connections are tight and insulated.
