TSIR04 is a USB relay with optically isolated inputs and OLED display and temperature sensor port.

It allows computer control switching of external devices by using the USB port of your computer. The communication medium also can be changed easily. Replace the USBBee module with a WiFiBee, it becomes a WIFI relay. It will be a Bluetooth relay when you plug a BluetoothBee. 

The TSIR04 provides four volt free contact relay outputs with a current rating of up to 10Amp each. The module is powered from a 5V/12V DC power supply. The DC input jack is 2.1mm with positive core polarity, The relays are SPDT types. 

 Optically Isolated Inputs

TSIR04 has 4 optically isolated input ports. Input voltage absolute max. 30V DC, Operational 4.5V to 27V DC. TSIR0x has 2 working modes:

Normal mode: When the board reads an input signal it recognizes the input state.

Auto mode: When the board reads an input signal it recognizes the input state and turns on the corresponding relay. When the input voltage is removed relay turns off. 

OLED display

OLED display shows the current board state. You can check the state no need to connect with your PC.

Current mode: Manual/Auto
IN1:0/1 RLY1:ON/OFF
IN2:0/1 RLY2:ON/OFF
IN3:0/1 RLY2:ON/OFF
IN4:0/1 RLY3:ON/OFF
Temperature: xxx  degree

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 TSIR04 is here: G5LA datasheet

Please choose the correct DC power supply for your board.

First Step - Install the Driver

TSIR04 module uses USBBee module as the USB extension port. USBBee 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.

Commands
The TSIR04 operates with an easy to use command set as described in the table below.

TSIR04 Baud rate: 9600 

Test program
To get the TSIR04 up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.

How long does it take to reach the USA, UK, Germany, Australia Canada and other EU countries?  

From China: If we ship from China, the delivery time can be from 7 working days to 15 working days. See the proof on the images below. US based orders are delivered more quickly than other countries.

Most of the USA, UK, Canada, Australia, and Germany  based orders are delivered within 7 days. However, because of customs related processes, it can sometimes take up to 15 days.  Check out all the shipment proof images on this page. 

 

From Australia: If you have chosen standard post, you will receive your parcel in 3-5 days (in Australia) and 5-7 days (outside Australia)

If you have chosen economy post, you will receive your parcel in 3-5 days (in Australia) and 15-25 days (outside Australia)
