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.
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.
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 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:
Now that you have everything together, let's start using the VCP1100!
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.
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 VCP1100.
After plugging the VCP1100 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 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:
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 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.
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.
