===About===
[[Image:REL1100_About.jpg|link=|600px]]

The REL1100 has four PWM-enabled solid-state relays. Control up to 4 devices that require up to 30V and 8A. You interact with the REL1100 through the Digital Output Channel Class to turn on and off power to your circuit or device. Using the Duty Cycle feature you can limit the power being supplied to a specific level. This allows you to control devices as a dimmer would.

===Explore Your Phidget Channels Using The Control Panel===

You can use your Control Panel to explore your Phidget's channels.

'''1.''' Open your Control Panel, and you will find the following channels:

[[Image:REL1100_Load_Diagram.jpg|link=|350px|right]]

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

[[Image:REL1100_Multi_Diagram.jpg|link=|350px|right]]

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.

{{UGC-Entry|High Power Applications ( > 50W )||
The Isolated Solid State Relay Phidget is capable of switching loads of up to 240W. However, for power higher than 50W, you will 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 [https://www.phidgets.com/docs/Solid_State_Relay_Primer hockey puck type SSR] may be a better choice.
