Elecbee 8-Channel 5V Relay Module with Optocoupler Isolation High/Low Level Trigger 250V AC/30V DC 10A Support for Arduino Raspberry Pi

Managing multiple high-voltage components with a low-power microcontroller often results in signal noise and potential hardware damage. This 8-Channel 5V Relay Module solves this by providing dual-stage optocoupler isolation, creating a physical barrier between your control circuit and the power load. Whether you are automating smart home systems, irrigation controllers, or industrial PLC outputs, this board ensures stable, interference-free performance.

This multi-channel relay board is designed for technical versatility. Each of the 8 channels can be independently configured to meet your specific project logic. The What includes:

• Trigger Mode: Selectable High or Low level trigger via S1-S8 jumpers.
• Output Interface: 8x Normally Open (NO) and Normally Closed (NC) contacts.
• Load Limit: Supports AC 250V/10A and DC 30V/10A per channel.
• Input Logic: 5V DC supply with IN1-IN8 control pins.

Technical product information: The module measures 141.55118.5mm and features a high-quality PCB with 3.1mm fixed screw holes for industrial mounting. The terminal blocks allow for solderless connections, making it an ideal microcontroller accessory for Arduino, Raspberry Pi, and 8051 systems. The opto-isolated trigger ensures a low 5mA drive current, reducing the strain on your MCU's I/O pins while maintaining high-frequency switching reliability.
