SmartElex 5V 3A 8 Channel Signal Relay Module
The SmartElex 5V 3A 8 Channel Signal Relay Module is a dependable switching solution built to control multiple electrical devices with precision. This 8 Channel Relay Module features eight JY4100F-S-DC5V-C relays, each capable of safely switching loads up to 3A at 120V AC or 24V DC. Designed to operate on a stable 5V supply, it offers individual input triggers and LED indicators for real-time status visibility.
With strong electrical isolation and seamless compatibility with Arduino, ESP32, and Raspberry Pi, this 5V relay module is well-suited for automation panels, IoT systems, and complex control applications where reliable multi-channel switching is essential.
Applications:
• Smart home automation (e.g., managing several appliances)
• Complex industrial automation systems.
• Robotics projects require several actuators.
• IoT systems have several relay outputs.
• Alarms, security, and access control panels
Cautions:
• Use a well regulated 5V supply with adequate current (at least 1A suggested).
• Ensure that relay load restrictions are not exceeded.
• To avoid electrical dangers, securely isolate all AC wiring.
• Maintain a dry, clean, and dust-free atmosphere.
Features:
• An 8-channel relay module with individual control.
• It operates at 5V DC and has active LOW/HIGH triggers.
• Each relay can handle 3A at 120V AC or 24V DC.
• Compatible with Arduino, ESP32, Raspberry Pi, and more platforms.
• Status LEDs for each channel are used to monitor operation.
• Fast switching: ≤10 ms operation and ≤5 ms release.
• Contact resistance of ≤100 mΩ enables stable conductivity.
• Total power usage is around 2.88W across all channels.
• High insulation resistance and dielectric strength are essential for safety.
• Suitable for -40°C to +85°C temperatures.
