Honeywell TP-DIKBTA-100 51196694-300 Integrated Keyboard Assembly

The Honeywell TP-DIKBTA-100, also cataloged as the 51196694-300 IKB Keyboard, serves as the primary TP-DIKBTA-100 operator interface component utilized to execute manual control and navigation across Honeywell Experion PKS and TotalPlant Solution (TPS) console platforms.

Hardware Specifications

Process Control Integration & Channel Isolation

• Tactile Feedback Control: The console layout integrates membrane-shielded, low-travel mechanical keys combined with dedicated HMI control zones. This ensures accurate operator input without the risk of double-strike errors during critical plant events.
• De-coupled Signal Filtering: The internal keyboard controller isolates physical key-switch matrices from the core console data bus through serial-encoded transmission lines, keeping any external ESD (electrostatic discharge) from propagating into backplane electronics.
• 4-20 mA Loop Protection Coexistence: The keyboard housing incorporates high-frequency shielding and ferrite-choked cabling to suppress radiated electromagnetic emissions, preventing HMI power lines from inducing noise into nearby low-voltage analog 4-20 mA HART loops.

Frequently Asked Questions

Q: Can the integrated trackball be field-cleaned if navigation becomes unresponsive?

A: Yes. The trackball collar can be rotated counter-clockwise to access and clean the internal optical sensors and physical rollers without demounting the entire keyboard assembly from the operator console deck.

Q: Is the TP-DIKBTA-100 hot-pluggable on Honeywell console ports?

A: No. To prevent logic circuit lockups or transient voltage spikes on the console interface controller, the console workstation should be powered down or placed into standby mode before disconnecting or reconnecting the keyboard assembly.

Field Installation Guidelines

• Chassis Ground Path Integrity: When installing the keyboard assembly into the console cutout, ensure that the metallic grounding strap on the rear frame makes clean metal-to-metal contact with the common cabinet earth frame.
• Cable Routing Paths: Route the heavy interface cable away from internal AC power distribution blocks and high-amperage cooling fans to prevent inductive signal distortion on the keyboard data bus.
• Mounting Alignment Protection: Lower the keyboard into the panel cutout evenly to avoid putting structural stress on the trackball housing, and hand-tighten all securing clips around the underside plate.
• Liquid Splatter Prevention: Ensure that the perimeter sealing gasket is seated properly between the keyboard bezel and the console cutout to protect internal electronics from environmental dust and spills.
