The 5V 8-Channel Solid State Relay Module Low Level Trigger is a compact multi-channel switching module designed for controlling AC electrical loads through microcontroller and embedded system outputs.
The module integrates eight independent solid state relay channels, allowing simultaneous control of multiple devices or circuits. Using solid-state switching technology instead of mechanical contacts, the module offers silent operation, fast switching speed, longer lifespan, and improved reliability.
The module operates using a 5V DC power supply and supports low-level trigger control, where each relay channel activates when the input signal voltage is between 0V and 2.5V. The relay remains OFF when the input signal voltage is between 3.3V and 5V.
For convenient wiring and secure connections, the board includes both 2.54mm header pins and blue KF301 screw terminals. Its compact design makes it suitable for automation systems, smart home control, industrial switching applications, and multi-channel embedded projects.
