Relay Module 1 Channel 5V with High/Low Level Trigger Selector
The Relay Module 1 Channel 5V with High/Low Level Trigger Selector is a highly reliable and versatile switching device designed to control high-voltage and high-current circuits using low-voltage control signals. Operating at 5V DC, this single-channel module is ideal for integration with microcontrollers, such as Arduino or Raspberry Pi, or other digital control systems requiring precise control of high-power loads. Its robust design and user-friendly features make it an excellent choice for technical writers documenting electronics projects for e-commerce platforms, catering to both hobbyists and professional engineers.
Features:
- Normally open and Normally closed.
- High-level trigger or low-Level trigger selection by a jumper.
- Optocoupler isolation.
- Terminal blocks for both input and output.
- Two LED indicators: power (green LED), the relay status (red LED).
- Fault-tolerant design, even if the control line is broken, the relay will not operate.
- Operating voltage (power): 5V.

Input Interface:
- DC+ : Connect the positive pole of the 5V power supply.
- DC- : Connected the negative pole of the 5V power supply.
- IN: Signal trigger input (3.3V to 5V, high or low level signal selected via a jumper).
Output Interface:
- NO: The normally open interface.
- NC: The normally closed interface.
- COM: The common interface for both normally open and normally closed.
High/Low level Trigger Selection Jumper:
- If the jumper is placed between COM and L, the relay uses LOW level trigger.
- If the jumper is placed between COM and H, the relay uses HIGH level trigger.
How it works
High Level Trigger:
- When IN is LOW level signal, the NO does not connect with COM and the NC connects with COM.
- When IN is HIGH level signal, the NO connects with COM and the NC does not connect with COM.
Low Level Trigger:
- When IN is LOW level signal, the NO connects with COM and the NC does not connect with COM.
- When IN is HIGH level signal, the NO does not connect with COM and the NC connects with COM.
Applications:
- Home automation systems for controlling lights and appliances.
- Industrial control systems requiring safe switching mechanisms.
- DIY electronics projects involving microcontroller-based control.
- Automated testing equipment for switching test loads.
- Smart home devices integrating relay-based control.
Package Include:
- 1 x Relay Module 1 Channel 5V with High/Low Level Trigger Selector.
