Honeywell 51400989-100 Operator Keyboard

Product Overview

The Honeywell 51400989-100 Operator Keyboard is a purpose-built industrial input device engineered specifically for Honeywell distributed control system (DCS) operator stations. Designed for continuous-duty control room operation, it delivers consistent tactile response, high legibility, and long-term reliability in mission-critical environments.

This keyboard integrates seamlessly with Honeywell operator platforms such as Experion PKS, TPS, and legacy TDC 3000 systems. Its robust construction and workstation compatibility make it suitable for console-mounted and desk-mounted operator stations where uninterrupted performance is required around the clock.

System Compatibility & Integration

The Honeywell 51400989-100 is validated for direct use with Honeywell operator workstations and console systems, including but not limited to:

• Global User Station (GUS)

• Universal Station (US)

• Experion Station variants including ES-T and ES-F

• Fixed and modular Honeywell control-room consoles

The keyboard operates with Honeywell-approved operating system images and HMI environments, ensuring stable recognition without additional drivers or configuration.

Mechanical Construction & Ergonomics

Built for control-room ergonomics, the keyboard features a full industrial QWERTY layout optimized for operator efficiency and reduced fatigue during extended shifts.

Key design characteristics include:

• Industrial-grade key assemblies designed for high actuation cycles

• Membrane or mechanical key technology depending on manufacturing revision

• High-contrast, wear-resistant key legends for clear visibility under low ambient lighting

• Rigid enclosure suitable for fixed console installation

The overall design prioritizes reliability, ease of cleaning, and consistent tactile feedback in 24/7 operational settings.

Electrical Interface & Power

The Honeywell 51400989-100 connects directly to operator stations using standard workstation interfaces supported by Honeywell hardware:

• PS/2 interface on legacy and transitional systems

• USB interface on newer Experion-based stations

The unit is powered directly through the interface connection, eliminating the need for external power supplies or adapters.
