TSRU430- 4 Channel 30A USB Relay Board

The TSRU430 provides four volt free contact relay outputs with a current rating of up to 30Amp each. The module is powered with a 12 VDC supply. The DC input jack is 2.1mm with positive core polarity, DC supplies are required to supply at least 1A at 12VDC. The relays are SPST-NO types.

It's a USB relay, you can easily control this relay module by your computer. The communication way also can be changed easily. Replace the USBBee module with a BluetoothBee, it becomes a Bluetooth relay. It will be a Wi-Fi relay when you plug a WiFiBee.

In addition, this module supports delay function that you can set each relay output delay between 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 TSRB430 is here: G8P datasheet 

First Step - Install the Driver 

USB Bee module uses a CP2102 USB to UART chip. Before using it, you need to download the CP210x Driver.

Connect the module to the computer's USB port and windows will detect it and ask for the drivers. Point windows to the inf folder and it will install the driver.

A new com port will now appear

Commands
The TSRU430 operates with an easy to use command set as described in the table below.

TOSR0x Baud rate: 9600 

Test program

To get the TSRU430 up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
