The RX2-4K controller is used to control devices connected to its relay outputs using keyfobs. It enables control of electrical devices such as parking barriers, gates, roller shutters, etc. The controller also has inputs and outputs designed to work with an alarm control panel, allowing it to be used for remote control of an alarm system.
