5V 8 Channel Relay Module Board

The 5V 8 Channel Relay Module Board is an essential component for anyone working on Arduino, IoT automation, or industrial control systems. This module allows you to switch up to eight independent AC or DC devices with low-power microcontroller signals, ensuring reliable, efficient, and isolated load control.

Each channel on the board uses an electromagnetic relay triggered by a standard 5V DC signal, enabling seamless integration with Arduino boards, ESP32, Raspberry Pi, and other popular microcontrollers.

The module includes optocoupler isolation to protect your control board from voltage spikes and surges — making it ideal for both DIY hobbyists and professional engineers.

🔧 Technical Specifications:

• Control Voltage (Input): 5V DC

• Load Voltage (Output): Up to 250V AC or 30V DC

• Load Current: 10A per relay channel

• Relay Channels: 8 independent relays

• Trigger Mode: Active low

• Isolation: Optocoupler isolation per channel

• Indicators: LED indicators showing relay status

• Terminals: High-quality screw terminals for secure wiring

• PCB Size: Medium-size board with mounting holes for easy installation

• Weight: Light and easy to mount in enclosures

With 5V DC control, this relay board easily connects to your Arduino Uno or Arduino Mega, and can be powered from a separate 5V supply if necessary using one of our recommended ElectroWay Power Adapters.

🛠️ Common Usage Scenarios:

✅ Home Automation Systems:
Turn on/off lights, fans, smart sockets, and home appliances remotely with an Arduino-based or IoT-connected system.

✅ Industrial Automation Projects:
Manage machinery, conveyor belts, or pumps by integrating this 8-channel relay board into larger automation control panels.

✅ Arduino & DIY Electronics Projects:
Ideal for robotics, security systems, or agriculture-based automation projects where multiple actuators or devices need independent control.

✅ Smart Energy Management:
Use it to automate and monitor energy consumption, load balancing, and smart grid projects using ESP32 and IoT frameworks.

The 5V 8 Channel Relay Module is trusted for multi-device control where reliability, safety, and isolation are essential for project success.

⚠️ Precautions & Usage Tips:

✅ Power Requirements: Ensure a strong 5V supply, especially if multiple relays are activated at once.
✅ Safe Wiring: Double-check AC wiring to prevent shock hazards; always use insulated tools and accessories.
✅ Cooling Advice: Provide ventilation or spacing if switching high loads continuously to prevent board overheating.
✅ Testing Recommended: Verify relay operations using test circuits before connecting real devices.
✅ Use Correct Relay Ratings: Do not exceed 10A load per relay to avoid damage or relay welding.
