About ABB SACO 16A3-AA Analog annunciator unit

ABB SACO 16A3-AA Analog annunciator unit 


SACO 16A3 is a versatile 16-channel analogue annunciator unit with two adjustable high set-points and two adjustable low set-points per channel. Simply by programming the annunciator chan-nels can be adapted to various transducer signal types such as current, voltage or resistance. Field contact signals are also accepted as channel input signals.



Precise Alarm Monitoring for Industrial Environments

Engineered for efficiency, the SACO 16A3-AA ensures real-time alarm indication via individual LED channels. Its low voltage signal compatibility, rapid response time, and microprocessor-based control make it a reliable fit for substation and industrial sites where safety and quick response are essential.


User-Friendly Operation and Flexible Installation

This annunciator unit supports both manual and remote reset options, with easy screw terminal connectivity and panel mounting. Self-diagnostic and testing functions simplify maintenance. The compact, light-grey, industrial-grade plastic housing provides IP52 protection, offering durability in demanding locations.

FAQ's of ABB SACO 16A3-AA Analog annunciator unit:


Q: How does the SACO 16A3-AA annunciator enhance alarm management in substations?

A: The SACO 16A3-AA streamlines alarm monitoring by providing highly visible LED indicators for each input channel, rapid sub-10ms response times, and reliable microcontroller-based processing. These features ensure prompt detection and signaling of abnormal events, improving operational safety and efficiency.

Q: What are the key benefits of the unit's galvanic isolation for input signals?

A: Galvanic isolation between inputs prevents electrical interference and ground-loop issues, protecting both the annunciator and connected devices. This results in safer operation and increased system reliability, especially important in industrial and substation environments.

Q: When should the self-diagnostic and test functions be used?

A: Self-diagnostic and test functions should be used regularly during scheduled maintenance or whenever confirmation of proper annunciator operation is needed. These features allow for proactive fault detection, ensuring system integrity and uninterrupted alarm reporting.

Q: Where can the SACO 16A3-AA be installed?

A: The SACO 16A3-AA is designed for panel-mount installation in control rooms, substation panels, or industrial environments. Its IP52 rating and operational temperature range from -20C to +55C allow safe use in a wide variety of indoor industrial settings.

Q: What is the process for resetting alarms on the SACO 16A3-AA?

A: Alarms can be reset manually through the unit's front panel or remotely via supported external controls. This flexibility facilitates swift restoration of normal operation after alarm events, minimizing downtime and enhancing user control.

Q: How does compliance with IEC standards benefit users?

A: Compliance with IEC 60255-6 and IEC 60255-27 ensures that the SACO 16A3-AA meets international requirements for protection, performance, and reliability, giving users confidence in its suitability for critical safety applications.
