The SmartElex 5V, 3A 2-Channel Signal Relay Module is a versatile dual-channel switching solution, ideal for controlling multiple medium-power loads. Featuring two high-quality JY4100F-S-DC5V-C relays, it can handle up to 3A at 120V AC or 24V DC per channel. Designed for seamless integration with microcontrollers like Arduino, Raspberry Pi, and ESP32, this module offers reliable switching performance with high isolation. It includes indicator LEDs for each channel and built-in protective features to ensure safe operation. With low power consumption and a wide operating temperature range, it’s a great fit for automation and IoT projects.
Features:
- Dual-channel relay module for controlling two loads.
- 5V DC operating voltage for easy integration.
- Each channel switches up to 3A at 120V AC or 24V DC.
- Ideal for microcontrollers like Arduino, Raspberry Pi, and ESP32.
- Fast response time with ≤10 ms operate and ≤5 ms release.
- Low power consumption (~0.36W per channel, ~0.72W total).
- Includes indicator LEDs for each channel’s status.
- High insulation resistance (≥100MΩ) for safety and reliability.
- Built-in protective features for safe operation.
- Operating temperature range: -40°C to +85°C for durability.
