Looking to add some serious digital inputs to your VINT Hub? This module has four active-high digital inputs ideal for reading switches, buttons, digital sensors, and other devices with a logic-level output. Each input can withstand up to ±30V from the devices it's connected to, and they trigger faster than ordinary VINT digital inputs, making it more likely to trigger from very brief changes.

Isolated for Stability

The VINT port on this board is isolated from the digital inputs, improving stability by removing unintentional ground loops from the system. Each input is also isolated from one another, reducing the amount of cross-channel interference.

Other Options

If you need a module with more isolated digital inputs per VINT port, or if you want a simpler, more cost effective solution, have a look at the "Compatible Products" tab.

Getting Started

Welcome to the DAQ1300 user guide! In order to get started, make sure you have the following hardware on hand:

Next, you will need to connect the pieces:

  1. Connect the DAQ1300 to the VINT Hub using the Phidget cable.
  2. Connect the VINT Hub to your computer with a USB cable.
  3. Connect a switch or digital sensor to one of the DAQ1300's inputs.

Now that you have everything together, let's start using the DAQ1300!

Using the DAQ1300

Phidget Control Panel

In order to demonstrate the functionality of the DAQ1300, the Phidget Control Panel running on a Windows machine will be used.

The Phidget Control Panel is available for use on both macOS and Windows machines. If you would like to follow along, first take a look at the getting started guide for your operating system:

Linux users can follow the getting started with Linux guide and continue reading here for more information about the DAQ1300.

First Look

After plugging the DAQ1300 into your computer and opening the Phidget Control Panel, you will see something like this:

The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

  • Serial number: allows you to differentiate between similar Phidgets.
  • Channel: allows you to differentiate between similar objects on a Phidget.
  • Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.

The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

Digital Input

Double-click on a Digital Input object in order to run the example:

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

  • This is an active-high device, therefore, it will be true when connected to a high voltage, and false when connected to ground.

Technical Details


The DAQ1300 features four isolated digital input terminals. Each input is isolated from all other inputs, which allows a single device to connect to a variety of sources, and prevents cross-channel interference.

Each input is active-high, meaning the (+) terminal must be pulled at least 2.5 volts above the (-) terminal to register as TRUE.

Example Use

Here are a few things you can do with the DAQ1300 Digital Input Phidget

Use With a Switch

DAQ1300 Switch Diagram.jpg

To interface a switch with the DAQ1300, an external voltage source must be provided to pull the input HIGH.

Multiple Sources

All inputs on the DAQ1300 are isolated from one another, so a variety of signals from different sources can be monitored with a single device.

Detecting an External Voltage

DAQ1300 Voltage Diagram.jpg

The DAQ1300 can be used without additional circuitry to detect the presence of a voltage on a line (from a power source or a signal), by wiring the input terminals to the line and its corresponding ground.

Digital Input Current

The current consumption of this device varies depending on the voltage applied at the input. It ranges from 1.6mA to 4.5mA, according to the curve below:
