SK108 is a industrial four channel wireless switch controller, it provides maximum four channel signal input and maximum four channel control output. It features simple interface and reliable performance. The parameters can be modified by PC software / UART command / remote controller (SK108-S). DIP switch on the module can used to change operating frequency (maximum 16 group), operation mode etc. Using this module, user can replace wired device with the wireless connection, which significantly reduce the cost and save much time.
Note: Below parameters base on 12V power supply/ 25℃ testing environment.
