annunciatoren

Annunciatoren is the Dutch plural form of annunciator and can refer to two related concepts: people who announce information publicly, and signaling devices in technical systems. In English, annunciator typically denotes the signaling device, while historical uses refer to heralds or messengers.

Historically, an annunciator was a herald or messenger responsible for delivering proclamations at royal courts and public events. Annunciators carried official notices, read decrees, and transmitted messages to the appropriate audiences, serving as a formal link between authorities and the public.

In modern technology, an annunciator panel is a display device used in process control to indicate the status of subsystems or alarms. It typically consists of a bank of indicator lamps, numeric or textual readouts, and optional audible alarms. Signals originate from sensors, switches, or controllers; the panel may be wired in hard logic or integrated with PLC/SCADA systems. Status indicators can be latched to remain visible until acknowledged, enabling operators to identify and respond to issues quickly.

Applications include power generation, manufacturing, critical infrastructure, and transportation. Annunciators help operators monitor complex systems, diagnose faults, and coordinate corrective action, contributing to safety and reliability in operations.
