51400990-100 | Honeywell | UWS Universal Workstation Operator Keyboard Module

Product Overview

The Honeywell 51400990-100 serves as the primary tactical human-machine interface (HMI) console for the Honeywell Universal Workstation System (UWS). This heavy-duty, 147-key hardware panel provides control room operators with direct, tactile entry for setpoint adjustments, alarm acknowledgment, and real-time process loop monitoring. We supply this operator console component exclusively in 100% brand new, original factory condition to ensure crisp key switch actuation, eliminate command input lag, and restore pristine data entry capability to legacy console bays.

Technical Specifications

Engineering Advantages

• Consolidates Complex Control Commands: The 147-key layout groups operational macros, numeric data blocks, and navigation triggers onto a single faceplate. This setup allows control room operators to switch graphic displays and adjust process loops instantly without a mouse.

• Fits Ultra-Low Profile Console Bezels: The slim 2 cm depth profile panel slides directly into shallow desktop cutouts, control arm enclosures, or sloped console desks without interfering with structural support braces or heavy under-desk wiring trunks.

• Withstands Intense Control Room Wear: The heavy-duty membrane and key switch substrate tolerate constant, repetitive finger strikes and resist surface penetration from industrial dust, dirt, and accidental liquid splashes on the console deck.

• Simplifies Drop-In UWS Retrofits: This panel shares the exact mechanical mounting dimensions (24 cm x 24 cm) and electrical connector pins of legacy UWS keyboard bays, enabling quick field replacement without drilling new holes or flashing interface firmware.

FAQs

• Can I install this keyboard inside a Class I, Division 1 hazardous processing area?

  No. CSA and FM agencies certify this specific module (51400990-100) strictly for ordinary, non-hazardous industrial environments. For explosive gas atmospheres, you must place the panel inside an approved explosion-proof, purged enclosure or look for intrinsically safe Honeywell alternatives.

• Is this an authentic, factory-fresh Honeywell part or a cleaned-up surplus pull?

  We guarantee this product is 100% brand new, authentic, and completely unused factory stock. It arrives in original manufacturer protective boxes with all original factory serial numbers, barcode trackers, and anti-static wrapping intact.

• What power connection precautions prevent internal component damage?

  Verify your auxiliary power rail delivers a stable 24V DC line before seating the power harness. Isolate the station power source completely during panel replacement to prevent inductive voltage arcs across the data pins, which can compromise the internal key matrix encoder board.
