USB io 39 channel card UIO-HMI-24
UIO-HMI-24 Digital Inputs/Outputs & DAQ board with
39 channels and USB/Bluetooth/RF connectivity ( depending upon different models).
Welcome to the world of Computer Automation. This usb io Board – UIO-HMI-24
is a perfect companion for all your computer automation projects where you require large number of
I/Os as well as DAQ capability.
We can connect the usb io card UIO-HMI-24 with USB / Bluetooth / RF to PC, laptop or
any Android device.( different models have different connectivity.) It has up to 39 digital & 8 analogue
I/Os that will help you to monitor various real world scenarios using switches & different kind of sensors to
monitor many parameters like Temperature, Pressure, Light, Touch, PH etc.
This card is not only good for monitoring various parameters but a perfect candidate for Data Acquisition & control applications.
It appears as a USB CDC ( Communications Device Class) device when connected to USB port of a
computer ( for USB based cards). This creates a Virtual Serial (COM) Port, which allows easy communication
with the card.
We can use any programming language that supports serial communications ( C, C#, C++, VB, VB.NET,
Perl, Java etc) to communicate with UIO-HMI-24 very easily. Easy to use commands are available
to communicate with UIO-HMI-24 which handle various tasks like Controlling Digital Inputs & Outputs and
getting analog data etc.
The controller provides up to 39 digital input & output pins. It has also got up to 8 analog input pins
and up to 4 PWM output pins. All pins will be individually configured as Digital Input or Digital output or
Analog input automatically as per input command on the fly.
Each Digital pin can support a TTL or Schmitt Trigger Input or a 3.3V output. Each analog pin will convert
analog voltage ( Between 0 to 3V) or Higher ( through voltage divider) into 10 bit resolution value. We can convert the
output to raw data or voltage. The raw data be converted into required form using conversion formulas.
Finally, we can interface any kind of sensor whether it is providing digital output or analogue output with
UIO-HMI-24 and monitored with the help of computer.
