This is a USB/Wireless Timer relay module, it allows the computer to control switching of external devices by using the USB port of your computer.
It has a wireless extension port, that can work with XBee or Bluetooth Bee or Wifly modules, which means now you can control your device by Zigbee or Bluetooth or Wi-Fi.
The TOSR08-D module can be powered by USB bus or DC power and provides two-volt free contact relay outputs with a current rating of up to 10 Amp each.
It also supports the delay timer function. You can set each relay output delay from 0 second - 24 hours.
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 TOSR08-D is here: G5LA datasheet
If you use DC Power, the input voltage should be DC 5V.
First Step - Install the Driver
The TOSR08-D module uses FT232RL USB to UART chip . Before using the TOSR08-D you will need to download the FT232RL Driver.
Connect the TOSR08-D and windows will detect it and ask for the drivers. Point windows to the inf folder and it will install the driver.
The TOSR08-D will now appear as a com port.
The TOSR08-D operates with an easy to use command set as described in the table below.
TOSR08-D Baud rate : 9600
To get the TOSR08-D up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
