Echo In-Line Brake Control Using One Control Auto

The Echo® in-line trailer brake controller is truly a brake control for the modern age. It plugs into the vehicle and wirelessly connects to a smartphone, allowing users to control and monitor all trailer brake activity right from a device. It comes with a customizable app for Apple or Android.

Most things in this day and age can be accessed or controlled from a smartphone. With the Echo®, that includes trailer brakes. Echo® is powered by a Bluetooth-enabled system that connects right to a smartphone. A phone becomes the brake control monitoring unit in the cab of the vehicle. There is no need for extra modules, controls, buttons, or knobs.

The Echo® trailer brake controller comes with a custom-designed app that can be downloaded for iOS or Android OS phones. With this app, the wireless brake control can connect to a smartphone and display brake control settings and activity. It also sends status updates and allows users to receive incoming calls while the app is running. Note: If the Bluetooth connection is lost, the brake controller will continue to function safely using the most recently programmed settings.

The Echo® in-line brake controller operates using a triple-axis motion-sensing accelerometer—an integrated circuit that produces smooth, safe stops every time. It is compatible with two to eight trailer brakes (one to four axles) and can be used with low-voltage or PWM wiring systems. Echo® is also compatible with cruise control and ABS brakes and has built-in reverse-polarity protection and short-circuit protection. It is backed by a limited lifetime warranty.
