Radio gate controller ROB-21 is designed for opening/closing gates or garage doors using remote controls and EXTA LIFE application. The controller can also be used to control electric strikes at the property's pedestrian gate. In the case of controlling gates, it is necessary to connect the controller to the appropriate input of the gate or garage door controller. ROB-21 has two inputs for connecting limit switches, due to which application indicates gate status: closed/partially opened/opened. Gate control mode allows the gate to be fully opened or partially opened to a set point. Wide range of power supply voltage 12÷24 V AC/DC allows for interaction with most gate controllers available on the market. Two channels with NO contacts ensure independent control of: gate, pedestrian gate, two gates, two pedestrian gates. Dimensions enable installation in Ø60 junction boxes or directly in the gate controller casing.
