Generating extremely precise voltages is easy with this Phidgets voltage output module. It is designed to interface with devices that are controlled by an analog voltage signal. Simply plug it in to a VINT port, and you'll be able to set a voltage in your program between -10 and +10 volts with 16 bit resolution (300μV) at a current of up to 5mA (See the Connection & Compatibility tab for a list of VINT Hubs). If the attached device draws more than 5mA and the voltage begins to drop below the value specified, a warning event will be launched so your program can take an appropriate action. This Phidget is factory calibrated to ensure output accuracy.
Need higher resolution? The output on this Phidget also has a 0 to 5V terminal that can be used instead of the ±10 terminal, yielding a resolution of 76μV. Both terminals are controlled as the same object in software and cannot be used at the same time.
This board is electrically isolated from input to output, protecting your system fom instability caused by unintentional ground loops. If you need update speed more than isolation or voltage range, have a look at the VINT 12-bit Voltage Output 4V.
This Phidget is a smart device that must be controlled by a VINT Hub. For more information about VINT, have a look at the VINT Primer. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs currently available:

Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.
Welcome to the OUT1002 user guide! In order to get started, make sure you have the following hardware on hand:
Next, you will need to connect the pieces:
Now that you have everything together, let's start using the OUT1002!
In order to demonstrate the functionality of the OUT1002, 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 icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel
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 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 OUT1002.
After plugging the OUT1002 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:
The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.
Double-click on the Voltage Output object , labelled Isolated 16-bit Voltage Output Phidget, 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:
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.
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.
You are now ready to start writing your own code for the device. The best way to do that is to start from our examples:
This Phidget is compatible with the VoltageOutput Examples.
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.
Some devices may require an analog voltage as a control input. The OUT1002 supplies a fixed voltage up to ±10V, which can be used to control such devices.
In addition, this device is isolated and can apply its voltage anywhere in an application circuit, independent of USB ground.
The OUT1002 may have an unpredictable output voltage for a very short time immediately after the device changes modes, or is turned on. If this is a problem in your application and you have no way to ignore it via software, we recommend using a solid state relay to switch the output on once it has stabilized.
To ensure maximum voltage precision across the device's full range, the OUT1002 Phidget should be subjected to a minimal current draw, ideally less than 5mA in ±10V mode. 5V mode should only be used to set a voltage in high-impedance applications.
However, in the event you plan to power a small load with this device, it will either be sourcing or sinking current when in use. When it's connected to a circuit with a lower voltage potential than its own voltage setting, current will be flowing out from the OUT1002 into the circuit, so it will be sourcing current. When it's connected to a circuit with a higher voltage potential than the voltage it's set to, current will flow from the circuit into the OUT1002 for a current sinking situation.
The OUT1002 can source or sink up to 26mA of current depending on the selected output voltage and mode. Please refer to the chart below to determine the amount of current that can be sourced or sunk.
For example, if the connected circuit is pulling 25mA of current, the OUT1002 will only be able to provide a maximum of 2V (in 0-5V mode), even if you try to set it to a higher value.
