When the 3.3V digital output mode of your VINT port is not enough, this output module adds four PWM-enabled solid state relay outputs to your system. Because it uses relay outputs, you can control more powerful devices that require up to 30V and 8A. LED strips, DC motors, power relays, fans and other small circuits are just a few examples of what can be controlled with this module. The REL1100 connects to a port on a VINT Hub. See the "Comaptible Products" tab for a list of hubs.



Low-Side Switching

Each solid state relay switches an external circuit to ground when enabled. This action allows completion of the circuit in order to power a load. The power to the load is supplied externally and should be connected in series with the load and the relay output. Alternatively, you could use a pull-up resistor on the input of your load and then switch the input to ground when you want it to turn off. Each channel has a ground terminal beside it to make wiring a snap, and each one leads to a common ground.

PWM Switching

In addition to switching at microsecond speeds, each relay output is also capable of pulse-width modulation; rather than simply switching on or off, you can select a percentage duty cycle to limit the power being supplied to a specific level. This allows you to control devices like a dimmer would, which is an important feature for LEDs, fans, and motors. Check the datasheet for your device to ensure that it is designed to be used with PWM (some devices such as incandescent or CF bulbs are not designed for dimming).

Isolated for Stability

The VINT port on this board is electrically isolated from the rest of the board, improving stability by eliminating ground loops.

Getting Started

Welcome to the REL1100 user guide! In order to get started, make sure you have the following hardware on hand:


Next, you will need to connect the pieces:

REL1100 Functional.jpeg
  1. Connect the REL1100 to the VINT Hub using the Phidget cable.
  2. Connect the VINT Hub to your computer with a USB cable.
  3. Connect the series circuit to one of the relay terminals.


Now that you have everything together, let's start using the REL1100!

Using the REL1100

Phidget Control Panel

In order to demonstrate the functionality of the REL1100, 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 REL1100.

First Look

After plugging the REL1100 into your computer and opening the Phidget Control Panel, you will see something like this:

REL1100 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 , labelled Digital Output Isolated, in order to run the example:

REL1100 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. Remember, the REL1100 simply acts as a switch to ground.
  • Use the Duty Cycle slider to start using pulse-width modulation. Rather than simply switching on or off, you can select a Duty Cycle to limit the power being supplied to a specific level. This allows you to control devices like a dimmer would.

Technical Details

General

Outputs on the RELL1100 behave similarly to a solid state relay - by toggling the state of the output, you can switch a circuit on and off. Specifically, changing the output state will switch a connection between the output and ground terminals. The outputs are also PWM-enabled, which means they can vary the intensity of the output by setting a duty-cycle.

These outputs are designed for use with DC voltages only.

Usage Examples

Basic Switching

REL1100 Load Diagram.jpg

To switch a load with the REL1100, connect the load and power supply to any pair of output and ground terminals, as pictured to the right. The load could be a larger relay, a solenoid, LEDs, light bulbs, motors, etc. Check the specification table on the product page for your Phidget to ensure that the voltage or current required by your load does not exceed the maximum.

Switching Multiple Circuits

REL1100 Multi Diagram.jpg

Multiple circuits with multiple supplies may be controlled by the REL1100 at the same time. Just be aware the grounds of all switched circuits will be shared, as all ground terminals on the REL1100 are connected internally.

High Power Switching

The Isolated Solid State Relay Phidget is capable of switching loads of up to 240W. However, for power higher than 50W, you'll need some form of cooling to keep the heat of the transistors down at normal levels. The REL1100's strengths lie in its multiple, high switching speed outputs. For high power projects, a hockey puck type SSR may be a better choice.
