The FOXBORO P0903CV Annunciator Keyboard is a dedicated alarm annunciation and operator interface device developed for Foxboro I/A Series Workstation Processors. It incorporates 48 switch positions in a 12-column × 4-row arrangement, with each position equipped with red and yellow LED indicators for clear visualization of alarm and operating conditions. The keyboard also includes horn silence and lamp-test functions, while its audible alarm system uses different tones to help operators distinguish between system events and process alarm priorities. Built for control-room and industrial workstation environments, the P0903CV provides a convenient centralized interface for monitoring alarms and responding to abnormal process conditions, helping operators improve situational awareness and maintain efficient plant operation.
The FOXBORO P0903CV is designed for centralized alarm annunciation and operator interaction within Foxboro I/A Series control environments. It can be used in control rooms, operator stations, process monitoring panels, and workstation installations to provide immediate visual and audible notification of equipment faults, process deviations, system alarms, and other conditions requiring operator attention.
The annunciator keyboard is particularly suitable for oil and gas facilities, chemical and petrochemical plants, power generation stations, refineries, water treatment facilities, pulp and paper plants, and other continuous-process operations. Its dedicated alarm switches, dual-color indicators, audible warning capability, and external audio support help operators quickly recognize alarm priorities and respond effectively to changing plant conditions.
