In a simple application where you need to switch a signal line on and off, the Signal Relay Phidget is a quick and easy solution. With a double-pole double-throw style relay, it can switch up to two signals of 60 watts of DC power or 125 VA of AC power each. By nature, this relay Phidget is isolated from load to control, so a power surge in the load side will not damage your VINT Hub or computer.



AC or DC Switching

For DC applications, you can switch a circuit of up to 120V or 2A, as long as the switching power is 60W or less (For example, 30V/2A or 120V/0.5A). Similarly, you can switch up to 2A or 240V AC, to a maximum of 125 VA of power (For example, 62V/2A or 240V/0.5A).

Other Options

This relay is specifically intended to switch signals. If you need a relay that can switch power to a device, take a look at the more powerful relay boards on the "Other Relays" tab.

Getting Started

Welcome to the REL2002 user guide! In order to get started, make sure you have the following hardware on hand:


Next, you will need to connect the pieces:

REL2002 Functional.jpeg
  1. Connect the REL2002 to the VINT Hub using the Phidget cable.
  2. Connect the VINT Hub to your computer with a USB cable.
  3. Connect the circuit to the the "C" and "NO" terminals


Now that you have everything together, let's start using the REL2002!

Using the REL2002

Phidget Control Panel

In order to demonstrate the functionality of the REL2002, 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. If you would like to follow along, first 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 REL2002.

First Look

After plugging the REL2002 into your computer and opening the Phidget Control Panel, you will see something like this:

REL2002 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 If your Phidget is listed in red, your firmware is out of date.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.

Digital Output

Double-click on a Digital Output object in order to run the example:

REL2002 DigitalOutput Example.jpg


General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

  • Toggle the state of the digital output by pressing the button.
  • Note: the REL2002 is not designed to be used with Duty Cycle.

Technical Details

General

1017 1 Relay Diagram.jpg

The REL2002 uses a double-pole double-throw switch, meaning it is capable of switching two circuits at once between two terminals each, as illustrated by the image on the right.

A relay is an electrically-controlled switch. For more information about how mechanical relays work and how to use them, check the Mechanical Relay Primer.

Use with an Interface Kit

REL2002 InterfaceKit Terminals Picture.jpg

In addition to plugging directly into VINT ports, the REL2002 relay can be used with Interface Kits that have a Digital Output and 5V supply (like the 1018).

REL2002 InterfaceKit Terminals Diagram.jpg

To connect the REL2002 to the Interface Kit, cut one end off a Phidget Cable. Connect the red and black wires to the 5V and G terminals of the Interface Kit, respectively, and the white wire to the OUTPUT terminal you want to control the relay. Plug the end that still has a connector into the REL2002.

To control the relay, open the DigitalOutput object for the channel the white wire is connected to. Setting the output state TRUE or FALSE will set the state of the relay.
