It is a 1-channel solid state relay board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc.

Features:
5V low level trigger solid state relay, output with resistive fuse (240V 2A).
It is a 1-channel solid state relay board, which can be controlled by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc.
Standard interface can be connected with microcontrollers.
With blue KF301terminal, more convenient for control line.
