TOSR08-D – 8 Channel USB/Wireless 5V Timer Relay Module

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

Test program
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.
