SmartElex 5V 3A 2 Channel Signal Relay Module

The SmartElex 5V 3A 2 Channel Signal Relay Module is a dependable 2-Channel Relay Module designed to switch and control multiple medium-power devices with precision. Powered by a stable 5V relay module design, it uses two JY4100F-S-DC5V-C relays, each rated to handle 3A at 120V AC or 24V DC, ensuring exact and consistent switching performance.

Its core function is to provide electrically isolated control between low-voltage microcontrollers and higher-voltage loads, making it safe and efficient for real-world applications. With onboard LED indicators, protective circuitry, and seamless compatibility with Arduino, Raspberry Pi, and ESP32, this module is a practical choice for automation systems, IoT solutions, and smart control projects.

Applications:

• Smart home systems have dual device control.
• Dual motor or light control in automation.
• IoT initiatives require various device management.
• robotics, alarms, and security systems.
• Industrial process control

Cautions:

• Provide a good 5V regulated supply.
• Do not exceed the rated voltage and current for contacts.
• Use isolation techniques for high voltage connections.
• Prevent moisture and dust collection on the PCB.

Features:

• A dual-channel relay module may control two loads.
• 5V DC operating voltage allows for simple integration.
• Each channel can switch up to 3A at 120V AC or 24V DC.
• Ideal for microcontrollers such as the Arduino, Raspberry Pi, and ESP32.
• Quick response time: 10 ms operation and 5 ms release.
• Low power usage (`0.36W each channel, ~0.72W overall).
• Includes status LEDs for each channel.
• High insulation resistance (100 M) ensures safety and reliability.
• Built-in safety features ensure safe operation.
• The operating temperature range is -40C to +85C for durability.
