Channel:
allows you to differentiate between similar objects on a Phidget.
Version number:
corresponds to the rmware version your Phidget is running. If your Phidget is listed in red,
your rmware is out of date. Update the rmware 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:
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 speci c level. This allows you to control devices
like a dimmer would.
Technical Details
General
The RELL1101 outputs behave similarly to a solid state relay - by toggling the state of the output, you can switch a
circuit on and off. Speci cally, 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
percentage duty-cycle.
These outputs are designed for use with DC voltages only.
