TOSR120B is an upgraded version of TOSR120. Compared to the TOSR120, the TOSR120B has 2 bypass buttons for each channel.
User can activate the relay in any situation by pressing the bypass button. TOSR120B can enable/disable the password protection. It can be set to latching or momentary outputs.
TOSR120B allows computer control switching of external devices by using the USB port of your computer. It also has a wireless extension port, can work with Xbee or BluetoothBee or WiFibee Module, so, you can control your device via ZigBee or Bluetooth or Wi-Fi.
The TOSR120B provides four-volt free contact relay outputs with a current rating of up to 10Amp each. It comes with one DS18B20 temperature sensor port.
The module is powered using a 5V DC power supply (or USB). The DC input jack is 2.1mm with positive core polarity and the relays are SPDT types. If you want to power it with DC 12V or 24V, you just need a 12V/24V-5V DC converter.
Note: Relay board default password is: 123456
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 TOSR120B is here: G5LA datasheet
If you use DC power, the Input voltage should be DC 5V.
First Step - Install the Driver
The TOSR120B module uses FT232RL USB to UART chip. Before using the TOSR120 you will need to download the FT232RL Driver. Connect the TOSR120 and windows will detect it and ask for the drivers. Point windows to the inf folder and it will install the driver. The TOSR120B will now appear as a com port.
The TOSR120B operates with an easy to use command set as described in the table below.
TOSR120B Baud rate : 9600
To get the TOSR120B up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
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)
