TOSR140 is the upgraded version of TOSR04. It supports password. It can be set to latching or momentary outputs. TOSR140 allows computer control switching of external devices by using the USB port of your computer.
It also has a wireless extension port that can work with Xbee or BluetoothBee or Wi-Fibee Module, so, you can control your device via ZigBee or Bluetooth or Wi-Fi.
The TOSR140 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 TOSR140 is here: G5LA datasheet
If you use DC power, the Input voltage should be DC 5V.
First Step - Install the Driver
The TOSR140 module uses FT232RL USB to UART chip. Before using the TOSR140 you will need to download the FT232RL Driver.
Connect the TOSR140 and windows will detect it and ask for the drivers. Point windows to the inf folder and it will install the driver.
The TOSR140 will now appear as a com port.
The TOSR140 operates with an easy to use command set as described in the table below.
TOSR140 Baud rate: 9600
To get the TOSR140 up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
