With the VCP1100, you can quickly and easily measure the current flow in an electronic circuit or device. Just put this current sensor in series with one of the power lines, and you'll be able to measure up to 30A of direct current. It connects to a port on a VINT Hub; you can find a list of hubs on the Connection & Compatibility tab.

Isolated for Stability

This Phidget is electrically isolated, so a power surge on the circuit you're measuring will not damage your VINT Hub or your computer. Isolation also improves stability by eliminiating potential ground loops.

VINT Hubs

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:

Image Part Number Price Number of VINT Ports
HUB0000_0 $30.00 6
SBC3003_0 $120.00 6

Phidget Cables

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.

Getting Started

Welcome to the VCP1100 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 VCP1100 to the VINT Hub using the Phidget cable.
  2. Connect the current source to the terminals of the Current Phidget, with the current flowing into the minus terminal and out the plus terminal.
  3. Connect the VINT Hub to your computer with a USB cable.


Now that you have everything together, let's start using the VCP1100!

Using the VCP1100

Phidget Control Panel

In order to demonstrate the functionality of the VCP1100, 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.

Windows

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

macOS

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 VCP1100.

First Look

After plugging the VCP1100 into your computer and opening the Phidget Control Panel, you will see something like this:

VCP1100 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.

Current Input

Double-click on the Current 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:

  • Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.

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 examples:

This Phidget is compatible with the CurrentInput 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 Software Overview page.

Technical Details

Isolation

The VCP1100 is electrically isolated, so a power surge in the circuit you're measuring would only damage the VCP1100- it won't damage your VINT Hub or your computer unless it exceeds the board's isolation voltage (50V) . Having isolation also helps prevent the formation of ground loops in your system.
