TSIR04 - 4 Channel Outputs ,4 optically Isolated Inputs USB Relay Module
20 or more $30.00
Description:
TSIR04 is a USB relay with optically isolated inputs and OLED display and temperature sensor port. Very powerful and easy to use. It allows computer control switching of external devices by using the USB port of your computer. The communication way also can be changed easily. Remove the USBBee module instead with a WiFiBee, it becomes a WIFI relay. It will be a Bluetooth relay when you plugged a BluetoothBee. Very convenient to use.
The TSIR04 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 types.
Optically Isolated Inputs
TSIR04 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 read a input signal. Reporting the input state.
Auto mode: When the board read a input signal. Reporting the input state and turn on the corresponding relay. When the input voltage removed, relay turn off.
OLED display
OLED display show the current board state. You can check the state no need connect with you PC.
| Current mode: | Manual/Auto |
| IN1:0/1 | RLY1:ON/OFF |
| IN2:0/1 | RLY2:ON/OFF |
| IN3:0/1 | RLY2:ON/OFF |
| IN4:0/1 | RLY3:ON/OFF |
| Temperature: | xxx degree |
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.,
First Step - Install the Driver
TSIR04 module use USBBee module as the USB extension port. USBBee module uses a CP2102 USB to UART chip. Before using it you need to download the CP210x Driver.
Connect the module to computer's USB port and windows will detect it and ask for the drivers. Point windows to the inf folder and it will install the driver.
A new com port will now appear
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 TSIR04 up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
