MINIMUM TECH FEATURES :

• 2 LEDs to indicate relay ON status
• Works with logic-level signals from 3.3V or 5V devices
• Opto-isolation circuitry for controller protection
• Onboard diode for current protection and fast response
• PCB includes 4 mounting holes (3.1 mm diameter) for easy installation

DESCRIPTION

• The 2CH-RELAY-OPTO-5V module is a high-quality dual-channel relay board engineered for use in home automation, industrial control, IoT systems, and general embedded projects.
• This module integrates two independent SPDT relays, each capable of switching up to 10A at 250VAC or 10A at 30VDC, making it suitable for operating lights, appliances, solenoids, motors, and industrial equipment.

Key Functional Highlights:

• Dual-channel design provides control over two separate circuits simultaneously.
• Optocoupler isolation between input signals and relay coil enhances protection for microcontrollers by preventing electrical noise, surges, or spikes from reaching the logic side.
• Operates at 5V control voltage, ensuring compatibility with Arduino, Raspberry Pi (with level shifting), ESP8266, ESP32, and other MCU boards.
• Each channel includes LED indicators, showing real-time relay switching status, making debugging simple.
• Capable of switching AC and DC loads with high reliability and long operational life.
