ABB SACO 16D1-AA Annunciator Unit

The ABB SACO 16D1-AA is a high-performance, 16-channel digital alarm annunciator unit designed for localized or remote supervision of power plants, industrial processes, and electrical substations. As part of the SPACOM system, it provides clear, instantaneous visual and audible signaling of fault conditions, allowing operators to react swiftly to system disturbances. The SACO 16D1-AA is highly regarded for its modularity and its ability to communicate with higher-level control systems (like DCS or SCADA) via the SPA bus.
