1 Channel Relay Module 5V High And Low Level Trigger Relay Control COM44

Description

The 1-channel relay module (5V) with high and low-level trigger control is a versatile component often used in DIY electronics and IoT projects. This relay allows switching of high-voltage devices like lamps, fans, or appliances using a low-power microcontroller such as an Arduino or Raspberry Pi.

Features:

1. Voltage: Operates on 5V input, making it compatible with most microcontrollers.
2. Trigger Modes: Can be triggered by both high and low logic levels, offering flexibility in control logic.
3. LED Indicators: Typically includes LEDs for power and trigger status indication.
4. Control Load: Capable of switching AC or DC devices up to a specified current rating, often around 10A at 250V AC or 30V DC.
5. Optocoupler Isolation: Many models include an optocoupler for electrical isolation between the control circuit and the high-voltage load, improving safety.
6. Interface: Comes with input pins for VCC, GND, and signal, and output terminals for NO (Normally Open), NC (Normally Closed), and COM (Common).

Applications:

• Smart home systems to control lights and appliances.
• Automated irrigation or water pump systems.
• Prototyping circuits requiring high-voltage device control.
