Multi-Voltage 2-Channel Solid State Relay Module for Arduino & More

Effortlessly control AC loads with our Multi-Voltage 2-Channel Solid State Relay Module. Available in 5V, 12V, and 24V versions, this low-level trigger relay is perfect for Arduino, Raspberry Pi, AVR, PIC, and other microcontrollers, providing reliable and silent switching for your projects.

Key Features:

• Multi-Voltage Options: Choose from 5V, 12V, and 24V versions to suit your specific control circuit requirements.
• Dual Channel Control: Independently control two AC loads (up to 240V 2A each).
• Solid State Reliability: Enjoy silent operation, longer lifespan, and faster switching speeds compared to mechanical relays.
• Low-Level Trigger: Easy to integrate with your microcontrollers. The relay activates when the signal trigger terminal receives a low voltage.
• Built-in Safety: Each output includes a resistive fuse (240V 2A) for enhanced protection.
• Compact Design: Measuring just 55mm x 33mm x 25mm, it's perfect for space-constrained applications.

Technical Specifications:

• Output Load: 240V AC, 2A per channel (resistive fuse protected)
• Dimensions (LWH): 55mm x 33mm x 25mm
• Net Weight: 21.5g

Detailed Specifications by Voltage Version:

Module Interface:

• DC+: Connect to the positive power supply (must match the voltage of your chosen relay module).
• DC-: Connect to the negative power supply.
• CH1: Signal trigger terminal for Relay 1 (low-level trigger effective).
• CH2: Signal trigger terminal for Relay 2 (low-level trigger effective).

Understanding Low-Level Trigger:

A "low-level trigger" means that the relay activates when the signal trigger terminal (CH1 or CH2) receives a voltage of 0V, or a voltage significantly lower than the positive power supply, close to the negative power supply. This is commonly achieved by connecting the trigger terminal to the ground (negative power supply) of your control circuit.

Applications:

• Home automation
• Robotics
• Industrial control
• DIY electronics projects
• Controlling lights, motors, and other AC appliances

Important Note: Ensure your module's power supply (DC+ and DC-) voltage precisely matches the voltage of the relay module you have selected. Incorrect voltage can lead to module damage.
