The SCALA door module is the ideal addition to the SCALA controller for decentralized cabling of the individual door components.|This is particularly advantageous when large distances have to be bridged between the location of the SCALA controller and the door or when the door components are to be connected directly to the door itself. In addition, the door module with its relay output and two analog inputs offers the option of controlling additional doors via the SCALA controller.|The SCALA door module is connected to the controller via the RS485 interface. The connection for controlling all other door components, such as the door opener, reader and door monitoring contact, is made on the door module.|The module and the connected SCALA reader are supplied with power by the controller via the RS485 connection. All other door components are supplied with power by a separate power supply.|The SCALA door module is equipped with comprehensive diagnostic options and status display.|The LED display directly on the module provides a quick overview of whether the door module is correctly connected to the controller. In addition, the operating status and the transmission quality to the controller are displayed.|In addition, the SCALA door module is equipped with integrated temperature and voltage monitoring.
