TOSR120B - 2 Channel USB/Wireless 5V Relay - (Password/Momentary/Latching/Bypass button)
20 or more $20.50
TOSR120B is an upgraded version of TOSR120. Compared to the TOSR120, the TOSR120B added 2 bypass buttons for each channel. User can active the relay in any situation by press 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 works with Xbee or BluetoothBee or WiFibee Module, So you can control your device via zigbee or Bluetooth or WiFi!
The TOSR120B provides four volt free contact relay outputs with a current rating of up to 10Amp each. one DS18B20 temperature sensor port. The module is powered from a 5VDC power supply(or USB). The DC input jack is 2.1mm with positive core polarity, The relays are SPDT types. If you want power it with DC12V 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 DC5V.
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.
Commands
The TOSR120B operates with an easy to use command set as described in the table below.
TOSR120B Baud rate : 9600
Test program
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.
