4 Channel USB Wireless Control Relay Module Support Zigbee Bluetooth WIFI Control
Introduce:
This is a multi-functional USB \/ wireless control relay module， easy computer control 4 relay switches to control any device you want to control. Of the highlights of the device with a wireless extension interface， can be an external the XBEE module or Bluetooth module， and even wifi module， wireless way to control relay. TOSR04 USB \/ wireless relay modules can either use a USB-powered can also use an external power supply， very convenient to use. Relay Japanese Omron Relay， reliable quality， rated current of 10A.

Relay power rating:
If the relay is used at a voltage or current exceeding this specification， the life of the contacts may be significantly shortened. A full datasheet for the relays used on the TOSR04 is here: G5LA datasheetIf you use DC Power ，the Input voltage should be DC5V.
Use these steps:
Installing the drivers
USB interface chip module TOSR04 FT232RL. Please download and install the driver before TOSR04. When you TOSR04 module is connected to the computer， Windows will prompt the discovery of new hardware， follow the prompts to set the drive to retrieve files folder and install the driver correctly after the installation is complete， there will be a new COM port in the Device Manager， as follows the figure below:

Control commands:
The TOSR04 module uses a series of simple control commands， ordained defined as follows:module communication baud rate: 9600

Test Procedure:
To save time， more convenient test TOSR04 of modules， we provide a small test program， you can use it to control each channel relay switch.

Package included:
1 x USB Wireless Control Relay Module
