SK509 - 5W bi-directional Industrial remote wireless 4 paths swith control module

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.

DIP function description:

DIP8—communication mode selection

ON – real-time mode ( In this mode, output sync to the input immediately once the input state changed) 

OFF - timing mode ( output sync to in the input at set time interval )

DIP7 - master/slave selection 

ON - the master  

OFF - the slave

DIP6 – time interval selection of timing mode 

ON – non pairing mode ( valid when DIP 5 is On )

OFF – pairing mode ( pair the module in this mode , valid when DIP 5 is On )

DIP5 - mode selection 

ON - normal working mode 

OFF - setting mode ( connect module to PC by SK108-S, set the parameters)

DIP4 ~ 1 - working frequency channel selection, 16 channels in total (default channel interval is 0.5M), frequency can be reset by PC. 

Relationship between DIP switches and working frequency channel:


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
