Schneider Electric SXW-UI-16 Fire Alarm Interface Unit

The Schneider Electric SXW-UI-16 SpaceLogic UI-16 Central I/O Module provides 16 universal inputs in a compact, two‑piece package that mounts on the SpaceLogic bus for modular, scalable building automation. The universal inputs can be configured to read Digital, Counter, Supervised, Voltage, Current, Temperature, and Resistive signals, enabling a single module to handle a mix of field devices such as sensors, energy meters, and status points within Schneider Electric's SpaceLogic/SmartStruxure ecosystem. Its two‑piece design lets you wire the terminal base ahead of installing the electronics, with a patented locking mechanism that doubles as a removal handle and protective covers that support convection cooling, while the modules connect via an integrated bus for a simple slide‑together assembly and hot‑swapping capability. As part of Schneider Electric's modular SpaceLogic Central I/O family, the UI‑16 delivers 16 independent channels and seamless expansion across multiple modules, leveraging a common power and communications bus to enable distributed sensing, energy monitoring, and integrated signaling within a broader building management or safety system.
