TOSR120B is an upgraded version ofTOSR120. 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.
TOSR120Ballows 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 a12V/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 TheTOSR120B module uses FT232RL USB to UART chip. Before using the TOSR120 you will need to download theFT232RL 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. TheTOSR120B will now appear as a com port.
Commands TheTOSR120B operates with an easy to use command set as described in the table below.
TOSR120B Baud rate : 9600
Test program To get theTOSR120B up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
