1 Channel 5V Relay Module with High/Low Level Trigger

1 Channel 5V Relay Module with High/Low Level Trigger
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.
