If the 3.3V digital output mode of your hub's VINT port is not powerful enough, or if you just need more digital outputs, this cost-effective output module has you covered. This board adds four 5V digital outputs to your VINT hub, allowing you to control LEDs, relays, and other logic-level electronics. See the Connection & Compatibility tab for a list of VINT Hubs.
Each digital output is capable of pulse-width modulation, allowing you to select a duty cycle between 0% and 100% power. This is particularly useful for dimmable electronics such as LEDs or fans. Wiring is simple since each output terminal has a ground terminal beside it, leading to the board's shared ground.
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 OUT1100 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 OUT1100!
In order to demonstrate the functionality of the OUT1100, 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 OUT1100.
After plugging the OUT1100 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 a Digital Output 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 DigitalOutput 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.
Starting from firmware version 110, using Phidget22 library versions 126.96.36.19990107 and later, this device supports the use of a failsafe feature to put your device in a safe state should your program hang or crash.
With this feature, each Digital Output channel on this device has its own independently settable failsafe timer.
If the failsafe is not enabled, the device will behave as it did before the addition of this feature, maintaining the last state or duty cycle it received until it is explicitly told to stop.
Enabling the failsafe feature for a channel starts a recurring failsafe timer. Once the failsafe timer is enabled, it must be reset within the specified time or the channel will enter a failsafe state. Resetting the failsafe timer will reload the timer with the specified failsafe time, starting when the message to reset the timer is received by the Phidget.
For example: if the failsafe is enabled with a failsafe time of 1000ms, you will have 1000ms to reset the failsafe timer. Every time the failsafe timer is reset, you will have 1000ms from that time to reset the failsafe again.
If the failsafe timer is not reset before it runs out, the channel will enter a failsafe state. For Digital Output channels, this sets the output to a FALSE state. On the OUT1100 this sets the output LOW. Once the channel enters the failsafe state, it will reject any further input until the channel is reopened.
To prevent the channel from falsely entering the failsafe state, we recommend resetting the failsafe timer as frequently as is practical for your applicaiton. A good rule of thumb is to not let more than a third of the failsafe time pass before resetting the timer.
Once the failsafe has been enabled, it cannot be disabled by any means other than closing and reopening the channel.
When you use a failsafe in your program, we strongly recommend setting up an error event handler to catch the Failsafe Error Event, to allow your program to catch the failsafe event.
If you want your program to try to automatically recover from a failsafe state, you can close and re-open the channel from the error event handler after determining a failsafe condition caused the event.
The digital outputs on the OUT1100 are slightly different than the digital outputs on Phidget InterfaceKit boards.
Here are a few things you can do with the OUT1100 Digital Output Phidget
To drive an LED with the OUT1100, simply attach the anode to one of the digital output terminals, and the cathode to the the corresponding ground terminal. The built-in series resistance will limit the current and keep the LED from burning out.
To control an SSR with the OUT1100, attach the positive + terminal to the output terminal, and the ground - terminal to the corresponding ground terminal on the OUT1100.
An inexpensive mosfet and flyback diode circuit can be used to control larger loads (such as relays) from the OUT1100. Be sure to use a Logic-Level MOSFET so that the +5V Digital Output is able to turn it on. Similarly, an NPN transistor could be used in place of the MOSFET, in cases where they may be easier to obtain.
In some applications, particularly where there is a lot of electrical noise (automotive), or where you want maximum protection of the circuitry (interactive installations, kiosks), electrical isolation buys you a huge margin of protection. Driving the LED causes the output transistor to sink current.
The maximum current through the transistor will depend in part on the characteristics of the optocoupler.
