Products for USB Sensing and Control
The REL2103 is a simple, easy to use, solid-state relay. Solid-state relays switch silently and quickly, and last much longer than mechanical relays. This Phidget connects to your computer through a VINT Hub.
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:

The REL2103 is a solid-state relay capable of switching up to 10 amps or controlling power up to 30V. You interact with the REL2103 through the Digital Output Channel Class to turn on or off the power to a circuit.
Double click on the Digital Output channel class under the port your REL2103 is connected to.
Before you open a Phidget channel in your program, you can set these properties to specify which channel to open. You can find this information through the Control Panel.
1. Open the Control Panel and double-click on the red map pin icon:
2. The Addressing Information window will open. Here you will find all the information you need to address your Phidget in your program.
See the Phidget22 API for your language to determine exact syntax for each property.
A solid-state relay is an electrically-controlled switch. For more information about how SSRs work and how to use them, visit the Solid State Relay Guide.
The two middle pins on the REL2103, labeled "SRC" give you access to the source of the MOSFETs used to switch your circuit. If you are switching a DC load, the setup will be advantageous as you can double the maximum current handled by this Phidget (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.
