Relay Module (1 Channel) Active High 5V

The Relay Module (1 Channel) Active High 5V is a versatile and widely used component in electronic and automation projects. It allows low-power digital signals to control high-power devices. Here’s a detailed description of the product:

Features:

1. Single Channel Relay:
   • Equipped with one relay channel to control a single device.
   • Ideal for switching a variety of devices including lights, fans, and other appliances.
2. Active High Trigger:
   • The relay is activated when a high-level signal (5V) is applied to the control pin.
   • Compatible with various microcontrollers and logic circuits that operate at 5V.
3. Operating Voltage:
   • Operates at 5V DC, making it suitable for use with common microcontrollers like Arduino, Raspberry Pi, and other development boards.
4. High Current and Voltage Rating:
   • Capable of switching high current loads (up to 10A at 250V AC or 30V DC).
   • Allows control of high-power devices with low-power control signals.
5. Isolation:
   • Optocoupler isolation between the control side and the high-power side to protect the microcontroller from voltage spikes and noise.
   • Ensures safety and reliability in operation.
6. Indicator LEDs:
   • LED indicators for power and relay status.
   • Provides visual feedback on the operational state of the relay module.
7. Screw Terminals:
   • Screw terminals for easy and secure connections to the load and power source.
   • Simplifies the wiring process.
8. Mounting Holes:
   • Equipped with mounting holes for easy installation in project enclosures.
