SmartElex 5V 3A 4 Channel Signal Relay Module

SmartElex 5V 3A 4 Channel Signal Relay Module

The SmartElex 5V 3A 4 Channel Signal Relay Module is a compact and reliable 4 Channel Relay Module designed to control four independent medium-power loads with precision. Powered as a 5V relay module, it integrates high-quality JY4100F-S-DC5V-C relays, each capable of switching up to 3A at 120V AC or 24V DC.

With dedicated trigger inputs and LED status indicators for every channel, it allows easy monitoring and accurate switching. This module directly interfaces with popular microcontrollers such as Arduino, ESP8266, and Raspberry Pi, making it ideal for IoT, home automation, and embedded control applications where safety, isolation, and consistent performance are essential.

Applications:

• Home automation (controlled lights, fans, and locks)
• Industrial machine control
• IoT multi-device projects.
• Robotics and Motor Control
• Security systems and alarms.

Cautions:

• Always utilize a properly regulated 5V power supply.
• Avoid exceeding the rated load capacity.
• Provide proper isolation for AC loads.
• Store the module in a dry, clean place.

Features:

• Four-channel relay module allows for independent control of four devices.
• Operates at 5V DC and has an active LOW/HIGH trigger.
• Each relay can handle up to 3A at 120V AC or 24V DC.
• Compatible with Arduino, ESP8266, Raspberry Pi, and more platforms.
• Each channel has its own set of LED indicators.
• Fast switching: ≤10 ms operation and ≤5 ms release time.
• Low contact resistance (≤100 mΩ) ensures effective operation.
• The total power consumption is around 1.44W over four channels.
• High insulation resistance and dielectric strength are essential for safety.
• Wide operational temperature range (-40°C to +85°C).
