For new systems and projects, we recommend using the following VINT products instead of this one. If you need more digital inputs than the five remaining ports on the VINT Hub, you can also add a Digital Input Phidget to your system.

Note: The 1012_3 is functionally the same as the 1012_2B, but some of the specifications have changed due to components shortages changing the parts we use. See the Specifications tab for more information.

Digital Inputs

The Digital Inputs are activated by an external voltage source, triggering on a wide voltage range: 4 to 30VDC. They provide built-in filtering, to eliminate false triggering from electrical noise. They can be used to convey the state of on/off devices, such as push buttons, limit switches, relays.

Digital Outputs

The Open Collector Digital Outputs can be used to directly control substantial devices, switching up to 30VDC at up to 2 Amps. The Output acts as a switch to ground, so the circuit you're switching will need an external power supply. Each output is protected from transient voltages typical when switching inductive devices - relays, solenoids, motors. The Outputs can be used to directly control devices requiring substantial power such as incandescent lights, high power LEDs, relays, solenoids, motors.

Comes Packaged with


  • Hardware mounting kit:
  • 4x M3 Bolts (2cm Length)
  • 4x Plastic spacers (5mm Length)
  • 4x M3 Nuts


You can protect your board from dust and debris by purchasing an enclosure. An enclosure will also prevent unintentional shorts caused by objects touching the pins on the bottom of the board or any terminal screws.

USB Cables

Use a USB cable to connect this Phidget to your computer. We have a number of different lengths available, although the maximum length of a USB cable is 5 meters due to limitations in the timing protocol. For longer distances, we recommend that you use a Single Board Computer to control the Phidget remotely.

Getting Started

Welcome to the 1012 user guide! In order to get started, make sure you have the following hardware on hand:

Next, you will need to connect the pieces:

1012 2 Connecting The Hardware.jpg
  1. Digital Inputs: By connecting a power supply and a switch (or the 5V pin of the 1012 and a switch) you can test the digital inputs of the 1012.
  2. Open Collector Digital Outputs: Connect a load (like a light bulb or LED) in series with a power supply and connect one end of the series to a digital output and the other to ground, as pictured.
  3. Connect the Phidget to your computer using the USB cable

Now that you have everything together, let's start using the 1012!

Using the 1012

Phidget Control Panel

In order to demonstrate the functionality of the 1012, 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.


To open the Phidget Control Panel on Windows, find the Ph.jpg icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel

Windows PhidgetTaskbar.PNG


To open the Phidget Control Panel on macOS, open Finder and navigate to the Phidget Control Panel in the Applications list. Double click on the Ph.jpg icon to bring up the Phidget Control Panel.

For more information, 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 1012.

First Look

After plugging the 1012 into your computer and opening the Phidget Control Panel, you will see something like this:

1012 Panel.jpg

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:

1012 DigitalInputAL Example.jpg

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 input and false when connected to ground.

Digital Output

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

1012 DigitalOutput Example.jpg

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

  • Toggle the state of the digital output by pressing the button. Remember, the 1012 simply acts as a switch to ground.

Finding The Addressing Information

Before you can access the device in your own code, and from our examples, you'll need to take note of the addressing parameters for your Phidget. These will indicate how the Phidget is physically connected to your application. For simplicity, these parameters can be found by clicking the button at the top of the Control Panel example for that Phidget.

The locate Phidget button is found in the device information box

In the Addressing Information window, the section above the line displays information you will need to connect to your Phidget from any application. In particular, note the Channel Class field as this will be the API you will need to use with your Phidget, and the type of example you should use to get started with it. The section below the line provides information about the network the Phidget is connected on if it is attached remotely. Keep track of these parameters moving forward, as you will need them once you start running our examples or your own code.

All the information you need to address your Phidget

Using Your Own Program

You are now ready to start writing your own code for the device. The best way to do that is to start from our Code Samples.

Select your programming language of choice from the drop-down list to get an example for your device. You can use the options provided to further customize the example to best suit your needs.

Code Sample Choose Language.png

Once you have your example, you will need to follow the instructions on the page for your programming language to get it running. To find these instructions, select your programming language from the Programming Languages page.

Technical Details

Open Collector Digital Outputs

For more information on the 1012's digital outputs, see the Open Collector Digital Output Primer.


All of the digital inputs have built-in filtering. This helps to eliminate false triggering from electrical noise. The input is first RC filtered by a 10k/100nF node, which will reject noise of higher frequency than 1kHz. This filter generally eliminates the need to shield the digital input from inductive and capacitive coupling that is likely to occur in the wiring harnesses.

Monitoring a Switch

A simplified schematic of a digital input on the 1012 - Phidget InterfaceKit 0/16/16.
Full-Sized Image

To test your digital input, wire it up to a switch as shown in the diagram. The power supply VS1 needs to be within 4.2-30V DC in order to guarantee a response from the digital input when the switch is closed.

Monitoring the Position of a Relay

Monitoring the position of a double-pole relay.
Full-Sized Image

If you have a double-pole relay (that is, a relay that is designed to close two switches at once with the same control input), you can switch a load with one pole, and monitor the state of the relay with the other pole. This can come in handy as a safety feature- if the relay were to fail, your software would normally not have any way of knowing.
