Capable of switching up to 10 amps of current in either AC or DC, If you're looking for a convenient way to control power for a circuit or device up to a maximum of 30V, this is the Phidget you need. Solid state relays switch silently and quickly, and last much longer than mechanical relays. This Phidget is isolated from input to output, so you don't have to worry about damaging your VINT Hub or computer if you have a power surge on the load side.
This Phidget can be controlled with a VINT Hub. For more details, see the Connection & Compatibility tab.
This Phidget can be controlled by a VINT Hub using a port in digital output mode. 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 and Phidget InterfaceKits that can be used with this device:

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 REL2103 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 REL2103!
In order to demonstrate the functionality of the REL2103, 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 REL2103.
After plugging the REL2103 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:
A solid state relay is an electrically-controlled switch. For more information about how SSRs work and how to use them, check the Solid State Relay Primer.
The two middle pins on the REL2103, labelled "SRC" give you access to the source of the MOSFETs used to switch your circuit. The main advantage of this is that if you're switching a DC load, you can double the maximum current of this Phidget (from 10A to 20A).
The white schematic on the left shows a simplified version of the REL2103's circuitry: An optocoupler that activates two MOSFETs. The black schematic on the right shows how you would hook up a DC circuit to take advantage of the increased maximum current.
This device doesn't have an API of its own. It is controlled by opening a DigitalOutput channel on the Phidget that it's connected to. For a list of compatible Phidgets with Digital Output, see the Connection & Compatibility tab.
You can find details for the DigitalOutput API on the API tab for the Phidget that this sensor connects to.
