ABB SACO 16A3

ABB SACO 16A3 is an analog annunciator unit for monitoring analog parameters in power plants and substations. The annunciator unit captures analog signals including temperature, voltage and current from field sensors. The annunciator unit supports four alarm setpoints per channel to trigger warning and trip signals. The annunciator unit stores up to thirty time-stamped events for historical fault review. The annunciator unit communicates via SPA bus to exchange data with other ABB automation devices.

ABB SACO 16A3 offers flexible signal configuration and local parameter adjustment on front panel. The monitoring module supports multiple standard input types for Pt and Ni temperature sensors. The monitoring module features self-supervision functions to detect internal hardware faults automatically. The monitoring module displays measured values through bar graph and numerical display modes. The monitoring module complies with CE EMC standards for reliable operation in industrial power environments.

ABB SACO 16A3 is widely applied in power station, offshore and industrial distribution control systems. The industrial spare part can replace aged annunciator units to restore analog monitoring functions rapidly. The industrial spare part matches original specifications for direct cabinet replacement. The industrial spare part has clear part marking for fast identification and stock management. The industrial spare part reduces system downtime during maintenance and overhaul work.
