Honeywell 51196694-300 TP-DIKBTA-100 Operator Interface Keyboards

The Honeywell 51196694-300, also cataloged as the TP-DIKBTA-100 Industrial Keyboard with Integrated Trackball, operates as a dedicated hardware component for human-machine interface (HMI) input execution within Honeywell Experion PKS (C200, C300) process control systems. This ruggedized operator interface assembly translates manual keystrokes and trackball physical vector movements into digital command strings to navigate operator consoles and modify system setpoints.

Hardware Specifications

Process Control and DCS Metrics

• Integrated Operator Tracking and Control: The module pairs an alpha-numeric matrix with an unsealed or optical trackball encoder directly onto a unified surface-mount logic plane. This configuration routes tracking and manipulation interrupts straight to the workstation communication link, enabling operators to manipulate runtime parameters on active DCS graphics without requiring a separate desktop mouse.
• Interface Circuitry and Shield Isolation Bounds: The keyboard internal controller translates mechanical switch closures into serialization formats compatible with standard console bus drops. High-grade shielding arrays envelope the logic board traces to enforce structural isolation boundaries, blocking electrical common-mode noise or nearby electrostatic fields from interrupting or distorting input tracking signals.

Frequently Asked Questions

Q: How is the trackball assembly protected against fine dust and liquid splashes typical in process rooms?

A: The TP-DIKBTA-100 uses an industrial sealed membrane perimeter layout beneath the keycaps to shield internal electrical contact traces. The trackball mechanism resides within an isolated mechanical cavity designed with drainage clearances to divert minor airborne debris away from the primary optical tracking sensors.

Q: What interface protocol does this keyboard module utilize to communicate with Experion PKS consoles?

A: The device interfaces via a dedicated console port cable configuration integrated directly behind the main housing. The internal encoder electronics handle translation directly into the active hardware interface registers of the host operator workstation, matching localized cursor updates during runtime display sweeps.

Field Installation Guidelines

• Chassis Layout Alignment, Clearance Constraints, and Mechanical Seating: Insert the 1.02 kg module assembly straight into the designated console panel cutout or desk mount tray. Secure the perimeter frame using the factory-aligned mounting points, verifying that the rear cable assembly clearance constraint is maintained at a minimum of 50 mm to prevent bend radius fatigue or pinching against the cabinet structure.
• Conductor Separation, Wireway Constraints, and Shield Grounding: Route the integrated interface connection cable through panel wiring tracks kept separated from heavy high-potential AC power mains or variable speed drive feeds. Connect the keyboard chassis grounding strap directly to the panel’s central copper earth ground bus bar to safely discharge static build-ups and protect the internal surface-mount components from high-frequency electromagnetic fields.
