Product Details：

Honeywell 51108306200 (51108306-200) is a desktop trackball input module designed for Honeywell TDC3000 DCS operator station,its main purpose is reliable operator input and convenient screen cursor control for legacy TDC3000 console. This trackball unit is the dedicated human input device matching the TDC3000 operator display console. Operators can move the cursor on the process graphic screen,select control points,pop up faceplates,adjust set values and acknowledge alarms by rolling the trackball and pressing the attached function buttons. It adopts dedicated proprietary communication interface to connect to the operator station main board,transmitting cursor displacement and button trigger signals stably to the console processor without signal delay or misread. It is equipped with mechanical dust-proof structure for the trackball core,suitable for long-time continuous operation in control room environment. It supports independent button function mapping,engineers can assign shortcut functions such as alarm confirmation and page switching according to operation habits. It can detect trackball stuck,button failure and communication disconnection events,recording timestamped fault information and uploading alarm prompts to the operator station system for maintenance arrangement. It is a classic spare HMI accessory for old TDC3000 projects. Many legacy control rooms still rely on this trackball instead of a mouse to operate the DCS graphics.

Key specifications：Desktop standalone trackball assembly,proprietary interface for TDC3000 operator console. It comes with function selection buttons for DCS operation. Operating temperature range is 0°C to +60°C. It supports button stuck,trackball jamming and communication loss fault diagnosis. The internal circuit board is conformal coated for dust and moisture resistance. Front panel trackball and function keys show operation feedback for quick on-site inspection.

This desktop trackball module is widely deployed in petrochemical,chemical,power generation and water treatment plants for legacy TDC3000 DCS maintenance and operator station renewal projects. It cooperates with Honeywell operator station main board,LCN adapter board and display unit to complete the whole console human-machine interaction function. As a core unit for trackball module and operator input,it is the original cursor control hardware of TDC3000 operator console. Clearly defined interface cable simplifies console wiring,input function test and periodic cleaning maintenance work for control engineers.
