Sentry 300 Control Board 500415 Vehicular Gate Operator Swing Gate Opener ( GREEN )
The Replacement Control Board is the brain of the Sentry 300 system and does not conform to the latest UL-325 Safety Standard for Monitored Entrapment.
The Sentry 300 control board features high quality components and industry leading ideas such as auto resetting fuses for motor protection. The old auto type fuse that blows and must be replaced has been designed out of this controller to avoid the unnecessary expense of buying fuses. Another patent pending item designed into the control board is the on-board potentiometers for adjusting stop limits.
Many other features have been designed into the control board to ensure superior operation for years to come. Attention to detail and quality parts makes the Sentry Automatic Gate Opener the First High Quality Gate Opener for the Do It Yourself Installer. USAutomatic appreciates the fact you have recognized the quality of the Sentry gate opener for your installation and would appreciate your comments on how we are doing so that we may continue to build and design products in the future that work the way you want them to.
