The Expansion Single Sort LON FTT10A module is a type of expansion module designed for the JACE 8000 Niagara Controller. It provides a single LON (Local Operating Network) FTT10A port, which allows for the connection of devices and sensors to the controller. This module is used to expand the capabilities of the JACE 8000, enabling it to communicate with a wider range of devices and systems. The LON FTT10A protocol is a widely used standard for building automation and control systems, and the Expansion Single Sort LON FTT10A module is designed to support this protocol. The module is compatible with various devices and sensors that use the LON FTT10A protocol, such as temperature sensors, humidity sensors, and lighting controllers. The module is typically used in building automation and control systems, such as in commercial and industrial buildings, to provide a centralized control and monitoring system for various building systems, including HVAC, lighting, and security. The module is also used in smart buildings and smart city applications, where it provides a scalable and flexible solution for integrating various devices and systems.
