TOSR04-D - 4 Channel USB/Wireless 5V Timer Relay Module

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 TOSR04-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 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 TOSR0x is here: G5LA datasheet

If you use DC Power, the Input voltage should be DC 5V.

First Step - Install the Driver
The TOSR0x module uses FT232RL USB to UART chip . Before using the TOSR0x you will need to download the FT232RL Driver.

Connect the TOSR0x and windows will detect it and ask for the drivers. Point windows to the inf folder and it will install the driver.

The TOSR0x will now appear as a com port.

Commands
The TOSR04-D operates with an easy to use command set as described in the table below.

TOSR04-D Baud rate : 9600 

Test program and example source code
To get the TOSR04-D up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
