USB Relays connect directly to your phone or tablet's USB, Micro USB or type C port (most phones will require OTG cable connected to charging port).

The AR-16 Relay Controller App is the ideal solution for hundreds of applications where control of external devices is needed. Connect the AR-16 Relay Interface to your Tablet or Phone's USB port and you have instant control of any electrical device that can be connected to a relay. Control lighting, motors, appliances, HVAC equipment, lock or gate solenoids, indicator panels, heaters, camera tilt and pan, robotics and thousands of other electrical devices. Great for field testing prototype products or testing equipment for reliability.

This App allows you to instantly energize or de-energize a relay from your tablet or phone's touch screen. The app's start-up screen allows you to control all 16 of the AR-16 relays. Touch the relay button for the desired relay and the relay will energize (button will turn red). Touch the button again and the relay will de-energize (button will turn green). Label the relay buttons as needed from within the App or just create a text file using Notepad on your desktop PC and then copy to the EECI folder on your tablet or phone. App storage is turned off by default but may be turned on under App Permissions. Storage may be left off and is only needed to save the app settings.

Use EECI's CO-USB cable (available with Standard USB or Micro USB connector) for connecting the AR-16 to your tablet (or phone's OTG cable).
