4 Channel Isolated 5V 10A Relay Module opto coupler For Arduino PIC AVR DSP ARM

Description

• Four Independent Relay Channels: The module includes four separate relay channels, allowing you to control up to four electrical circuits or loads independently.
• Optocoupler Isolation: Each relay channel is optically isolated from the control circuit, ensuring electrical separation and protection. This isolation prevents voltage spikes and noise from affecting the control circuit, enhancing safety and reliability.
• High Current Capacity: The relays on the module are rated for high current handling, with a typical capacity of up to 10A at 250V AC or 30V DC. This makes the module suitable for controlling devices with moderate to high power requirements.
• Low-Level Trigger Input: The relays are activated with a low-level trigger signal, making them compatible with a wide range of microcontrollers, including Arduino, PIC, AVR, DSP, ARM, and more.
• LED Indicators: Each channel is equipped with an LED indicator that provides a visual indication of the relay’s state (on or off), allowing for quick status checks.
• Screw Terminal Blocks: The module typically includes screw terminal blocks for secure and convenient connection of external wires, simplifying the wiring process.
• Operating Voltage: The module operates at a low control voltage of 5V, which is compatible with most microcontroller systems and digital logic circuits.
• Versatile Applications: Suitable for a wide range of applications, including home automation, robotics, industrial control systems, DIY projects, prototyping, and more.
