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 MΩ) ensures safety and reliability. Built-in safety features ensure safe operation. The operating temperature range is -40°C to +85°C for durability.
