Getting Started

Checking the Contents

You should have received: An SSR Relay board An SSR Relay connector cable		In order to test your new Phidget you will also need: A PhidgetInterfaceKit 8/8/8 or PhidgetTextLCD A USB cable A 9V batter, a battery connector An incandescent bulb

Connecting the Pieces

Connect the positive/red wire from the battery to one output terminal of the SSR Board Connect negative/black wire from the battery to one of the bulb wire. Connect the bulb wire to the other output terminal of the SSR board. Attach the SSR Board to your PhidgetInterfaceKit by connecting a wire from the terminal block marked with a + to a digital output and another wire from the terminal block marked with a - to any ground terminal on the InterfaceKit. Connect the PhidgetInterfaceKit Board to your computer using the USB cable.

Testing Using Windows 2000 / XP / Vista / 7

Make sure you have the current version of the Phidget library installed on your PC. If you don't, follow these steps:

1. Go to the Quick Downloads section on the Windows page
2. Download and run the Phidget21 Installer (32-bit, or 64-bit, depending on your system)
3. You should see the icon on the right hand corner of the Task Bar.

Running Phidgets Sample Program

Double clicking on the icon loads the Phidget Control Panel; we will use this program to ensure that your new Phidget works properly.

The source code for the InterfaceKit-full sample program can be found in the quick downloads section on the C# Language Page. If you'd like to see examples in other languages, you can visit our Languages page.

Updating Device Firmware

If an entry in this list is red, it means the firmware for that device is out of date. Double click on the entry to be given the option of updating the firmware. If you choose not to update the firmware, you can still run the example for that device after refusing.

Double Click on the icon to activate the Phidget Control Panel and make sure that the Phidget InterfaceKit 8/8/8 is properly attached to your PC.
Double Click on Phidget InterfaceKit 8/8/8 in the Phidget Control Panel to bring up InterfaceKit-full and check that the box labelled Attached contains the word True. Turn the bulb on and off by clicking on the Digital output box. The bottom row of the digital out shows the status of the request, while the top row displays the status of the digital output as reported by the 3052 Relay.

Testing Using Mac OS X

1. Go to the Quick Downloads section on the Mac OS X page
2. Download and run the Phidget OS X Installer
3. Click on System Preferences >> Phidgets (under Other) to activate the Preference Pane
4. Make sure that the is properly attached.
5. Double Click on in the Phidget Preference Pane to bring up the Sample program. This program will function in a similar way as the Windows version.

Using Linux

For a step-by-step guide on getting Phidgets running on Linux, check the Linux page.

Technical Details

Solid State Relays

Solid State Relays, or SSRs, are devices designed to operate like standard relays but without mechanical motion. Built instead out of silicon transistors, SSRs allow currents and voltages to be switched by simple digital signals from a microprocessor or any other device that can supply the small amount of current needed to activate the SSR’s internal switching mechanism. For more information on solid state relays, refer to the SSR Primer.

Protection Devices

The SSR Board is safe to use with sensitive control devices like microprocessors, and will not damage a Phidget device or your PC. Optoisolation between the control inputs and outputs of the SSR in the form of a GaAs LED paired with a set of optically-controlled MOSFETs provides protection from output to input. An on-board 47V bidirectional transorb across the relay output protects the board from static electricity and surges from inductive loads.

Using the SSR Board

Using the SSR Relay Board in your application is typically done according to the diagram on the right, though there are other implementations for it as well.
