Honeywell TP-DIKBTA-100 / 51196694-300 Integrated Keyboard Module

Configured for desktop operator navigation and real-time process data entry in Honeywell Experion and legacy DCS platforms, the Honeywell TP-DIKBTA-100 / 51196694-300 (TP-DIKBTA-100 Integrated Keyboard Module) provides direct physical signal execution across dual-interface control consoles.

Suffix Breakdown & Model Matrix

• TP-DIKBTA-100: Base hardware designation identifying the desktop Integrated Keyboard with trackball assembly (IKB).
• 51196694-300: Orderable assembly part number configured with an IBM PS/2 protocol trackball cursor interface.

Hardware Specifications

Cold Junction & Field Bus Signal Integrity

The hardware integrates dedicated channel-to-channel isolation across internal encoder circuitry to eliminate signal interference during continuous operator manipulation. While field-level process transmitters utilize 4-20 mA HART loop protocols or FOUNDATION Fieldbus connectivity, this station interface maintains galvanic separation between high-frequency keyboard matrix scanning lines and the desktop workstation console ground, preventing common-mode noise propagation into sensitive process control networks.

Frequently Asked Questions

Q: Can the 51196694-300 trackball assembly be hot-swapped during active DCS workstation operation?

A: No, hot-swapping the PS/2 cursor interface while the operator console is powered can cause interface controller latch-up or driver failures. Always isolate terminal power or issue a station console shutdown before disconnecting the bus.

Q: How does the Relegendable Function Key Panel (RFKP) maintain contact execution reliability over high cycle counts?

A: The RFKP uses sealed tactile switches beneath clear protective covers, allowing custom label inserts without exposing the internal contact traces to physical debris or control-room atmospheric contaminants.

Q: Does the trackball module require a dedicated power rail external to the main console cable?

A: No, the integrated IBM PS/2 protocol trackball draws required operating voltage directly from the primary workstation host interface connection.

Field Installation Guidelines

Mount the unit directly on flat control-room workstation surfaces, ensuring sufficient clearance behind the rear enclosure to prevent excessive strain on the PS/2 and keyboard interface cables. Route communication lines through dedicated console cable channels, keeping a minimum clearance of 200 mm from high-voltage AC distribution wiring to eliminate electromagnetic noise interference. Secure all shield drains to the main station ground bus bar (single-point grounding) to preserve noise immunity across the full operator workstation loop.
