Honeywell 51403578-100 Operator Keyboard for TDC 3000 Stations

The Honeywell 51403578-100 operator keyboard gives control room staff direct access to TDC 3000 process displays. Engineers fit this unit when keypads wear out or stations need refurbishment. Moreover, it restores responsive operator input without replacing the entire console.

Physical Dimensions and Key Layout

The 51403578-100 fits the standard keyboard recess on TDC 3000 operator consoles. Its panel measures approximately 483 mm in width and 178 mm in height. Furthermore, the unit weighs roughly 1.6 kg, which eases handling during console service.

Key Count and Functional Groups

This operator keyboard provides a full alphanumeric block alongside dedicated function keys. The Honeywell 51403578-100 groups process navigation keys separately from data entry keys. Additionally, tactile key switches confirm each press with clear feedback. Consequently, operators enter setpoints quickly without misreading keystrokes.

Interface and Diagnostics

The keyboard connects to the station processor through a standard serial interface cable. Status LEDs report power presence and communication activity during operation. Therefore, technicians can confirm keyboard health without opening the console.

Integration and Maintenance Notes

The 51403578-100 operates inside TDC 3000 operator consoles and control rooms. Its drop-in outline allows quick exchange during scheduled maintenance windows. Meanwhile, the tactile key design shortens operator training time on new consoles.
