2pcs/lot SK108U 100mW- 5W bi-directional switch control industrial four channels  remote control  PC remote control & serial control switch rf module 

 

 

Include in the package:

1pcs SK108-Tx remote control transmittor rf modules(100mW-5W)

1pcs SK108-Rx remote control receiver rf  modules

2pcs SW433-XP1M Sucker antennas (cable length:1 meter)          

1pcs power supply adaptor (1W)

1pcs power supply adaptor (1W-5W)

 

 

 Pice is according to the SK108-Tx transmitter,1 set is about USD61.00-USD142.00.

Description 
 
 SK108U includes SK108U-Tx and SK108U-Rx. SK108U-Tx is an industrial serial control transmitter, it works with SK108U-Rx to build wireless switch control system. SK108U-TX is serial interface which can connect with PC and other serial devices.
 
One SK108U-Rx has 4 channels relay output. One SK108U-Tx can control multiple SK108U-Rx. The frequency of the SK108U-Tx and SK108U-Rx can be set to avoid frequency interference.
 
In hardware SK108U-Tx is the same as our SV series module, which has different output power and different interface for option.

SK108U-Rx is same as SK108 in hardware but different firmware.

Application circuit

The typical schematic circuit is as below:

 

 

 

 

Typical application: 

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:


 

Pin Definition:

 1) Four channels output(LED Light and relay) SK108U-RX Module has total 4 channels output(OUT1~OUT4),the status of output (open/close ) is controlled by SK108U-Tx.
2) DIP switch Settings(valid when power on again)
DIP8—Pull to “ON ” position
DIP7—Pull to “ON ” position
DIP6—Reserve
DIP5—Mode selection
ON—Normal working mode
OFF-- Configuration mode
DIP4~1—Working frequency channel selection,total 16 groups, frequency is configurable by PC software.

How to connect Antenna: The antenna is important in the communication. For this module, the match impedance is 50 Ohm. We have many kinds of antenna for customer to choose, please contact the corresponding sales engineer for help, or find the antenna in our website.

 


 

 Tips for antenna:

*Don’t close to the ground, metal, magnet, big current;

*If you are using the sucker antenna, pull the wire as straight as possible, the sucker foundation should stick with metal
