The REL2002 is a mechanical relay. The Signal Relay is a double-pole double-throw style relay meaning it will switch two circuits at once. This Phidget connects to your computer through a VINT Hub.

Features:

  • Capable of switching two circuits at once
  • Rated for 60W of DC power or 125 VA of AC power
  • DC applications - switch a circuit of up to 120V or 2A, to a maximum switching power of 60W (For example, 30V/2A or 120V/0.5A).
  • AC applications - switch up to 2A or 240V AC, to a maximum of 125 VA of power (For example, 62V/2A or 240V/0.5A).

Technical Details:

  • Isolation - A voltage spike on the load side of the relay will not damage the control side

VINT Hubs and InterfaceKits

This Phidget can be controlled by a VINT Hub or any other device with a digital output. 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:

Part 1: Setup

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!

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.

Windows

To open the Phidget Control Panel on Windows, find the Ph.jpg icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel

Windows PhidgetTaskbar.PNG

macOS

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 Ph.jpg 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 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.

Part 2: Using Your Phidget

About

1017 1 Relay Diagram.jpg

The REL2002 is a mechanical relay suitable for both AC and DC applications. It is a double-pole double-throw style relay meaning it will switch two circuits at once. You interact with the REL2002 through the Digital Output Channel Class to turn power to your circuit or device on and off .

Explore Your Phidget Channels Using The Control Panel

Double click on the Digital Output channel class under the port your REL2002 is connected to.

Part 4: Advanced Topics and Troubleshooting

How do I know what channel, serial number, or hub port to use in my program?

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:

The locate Phidget button is found in the device information box

2. The Addressing Information window will open. Here you will find all the information you need to address your Phidget in your program.
