TSIR04B – 4 Channel Outputs- 4 optically Isolated Inputs Wi-Fi Smartphone Relay
TSIR04B is similar to TSIR04. We have removed the OLED display and put the relay board in a plastic enclosure.
This is a TSIR04B Wi-Fi version relay board with optically isolated inputs and temperature sensor port. You can easily control this relay board by your computer or smartphone using Wi-Fi.
The communication method also can be changed easily. Replace the WiFiBee module with a BluetoothBee, it becomes a Bluetooth relay. It will be a USB relay when you plug a USBBee.
The TSIR04B 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 type.
Optically Isolated Inputs
TSIR04B 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.
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.
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 TSIR0x up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module. We also provide a FREE android/IOS App TSIR WiFi. You can control your device by your phone very easily.
