The AR-8 Relay Controller App is the ideal solution for hundreds of applications where control of external devices is needed. Connect the AR-8 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 utilizes the most recent USB interface technology developed by Prolific Technology Inc., a worldwide leader in USB interfacing.

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 8 of the AR-8 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 your tablet.

Use EECI's CO-USB cable (available with Standard USB or Micro USB connector) for connecting the AR-8 to your tablet or phone. Use the CC-USBB1 to connect the AR-8MF (may require CO-OTG adapter).

The AR-8 Relay Controller App has been developed to run on Android operating systems Android 3.2 through Android 11, which includes Honeycomb, Ice Cream Sandwich, Jelly Bean, KitKat, Lollipop, Marshmallow, Nougat, Oreo, Pie, Q and Red Velvet Cake. Root permission or special driver not needed for most Android phones and tablets that use the Android operating system 3.2 or higher (Honeycomb and up), just enable USB Host Mode.

Free telephone support is provided for this app by contacting EECI Support at or (937) 349-6000.

Event Notification for your Smartphone

Event Notification for your Smartphone

This software allows Text Message Alerts or Email Alerts to be sent to Smartphones, computers, tablets and other devices for the purpose of event notifications. Events that you may wish to send to your Smartphone include security system alarm alerts (such as alarm in progress, an open door, a tripped motion detector, broken window or smoke alarm). Other uses include alerts when room temperature or freezer temperature fall below a preset level. Any device with a contact closure or a voltage output may be connected to inputs on the AR-8MF, AR-12MF, STA-16 and other EECI products to trigger a text message alert to your Smartphone or computer. Other uses include alerts sent when a driveway sensor is tripped, a doorbell is sounded, a swimming pool activity alarm goes off, a security camera detects activity or any one of thousands of events that may need to be monitored. Are you a business owner and need to be alerted if a freezer has failed to keep food frozen? ...or maybe you need to know the time that your store door was unlocked. Managers need to be keep aware of the temperature of conference or banquet rooms. Maintenance personnel need to know the operating performance of HVAC equipment. EECI's free Notification Software will send a text message alert to your Smartphone when any of these events take place or at a pre-defined time interval.
