4 Channel Relay Module 5v with Optocoupler

The 5V 4-Channel Relay Module is designed to control multiple high-current electrical devices using low-voltage control signals from microcontrollers. It provides four independent relay channels, making it suitable for automation, industrial control, and embedded system applications. The module supports direct interfacing with popular microcontroller platforms such as Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, and other TTL logic circuit.

FEATURES:

• Operates on a 5V DC supply with four independent relay channels.
• Supports low-level triggering (0–2.5V) for reliable switching.
• Each relay channel requires approximately 15–20mA of driving current.
• Equipped with high-power relays rated for up to 10A at 250V AC or 10A at 30V DC.
• Compatible with a wide range of microcontrollers and digital control systems.
• Includes LED status indicators for easy monitoring of relay activation.
• Standard input and output interfaces simplify integration into electronic projects and control systems.
