Product overview
SK509 is an industrial four channels wireless switchcontrol module with pairing function, it provides maximum four channel signalinput and maximum four channel control output. It features in simple interfaceand reliable performance. The parameters can bemodified by PC software / UART command / remote controller (SK509-S). DIPswitch on the module can used to change operating frequency (maximum 16 group),operation mode etc. Using this module, user canreplace wired device with the wireless connection, which significantly reducethe cost and save much time.

Application Connection:
The input port is pulled up internally, leave open or connect with 3.3V will result in high level, it is low level when connect to GND.
High level will make the output of the other side short out. And low level will make the output of the other side open. Below is regular connection:
