2-Channel 5V Relay Module with Optocoupler

2-Channel 5V Relay Module with Optocoupler

Control two high-voltage devices independently from a single microcontroller with this versatile 2-Channel 5V Relay Module. This board is an essential building block for advanced home automation, robotics, and IoT projects, allowing you to switch two separate AC or DC loads using low-voltage signals from your Arduino, Raspberry Pi, or ESP32.

Each of the two channels features a high-quality Songle relay capable of handling loads up to 10A. The board is designed for maximum safety and reliability, with each channel isolated from your microcontroller using an onboard optocoupler. This protects your sensitive electronics from high-voltage spikes and electrical noise from the load circuit.

The module also includes a jumper (JD-VCC) that allows you to provide a separate power supply for the relays, further enhancing the electrical isolation. Onboard LEDs provide a clear visual indication of the power status and the activation state of each of the two relays, simplifying testing and debugging.

Key Features:

• Channels: 2 (Independently Controllable)
• Control Signal Voltage: 5V TTL
• Max Load (AC): 10A at 250V AC
• Max Load (DC): 10A at 30V DC
• Enhanced Safety: Onboard optocouplers for each channel
• Indicators: Power LED and individual status LEDs for each relay
• Flexible Powering: JD-VCC jumper for isolating relay power

Applications:

This 2-channel relay module is perfect for projects that require switching multiple devices, such as multi-zone lighting control, controlling both a fan and a pump in an automated greenhouse, robotics with multiple actuators, or any project where two high-power circuits need to be controlled independently.
