Product Details：

Honeywell 51195066100 (51195066-100) is a dedicated display interface board for Honeywell TDC3000 operator station,its main purpose is high-resolution video signal generation and stable graphics output for the original CRT monitor of legacy DCS console. This board receives graphic data,trend curves,alarm banners and control faceplate information from the operator station main processor,converts digital image data into analog RGB video signals and synchronizing pulses,and transmits the video signal to the CRT display unit for real-time process picture rendering. It adopts built-in signal compensation circuit to maintain stable image definition and synchronization,avoiding screen flicker,rolling picture and color distortion caused by long video cable transmission. It supports multiple standard display resolution modes matched with TDC3000 proprietary console monitors. Engineers can adjust image position and synchronization parameters through on-site configuration menu. It continuously monitors video output signal,horizontal/vertical sync circuit and internal hardware health. If the sync signal is lost or the graphics output circuit fails,it will record timestamped fault logs and show black screen or out-of-sync alarm on the monitor for maintenance arrangement. It is a scarce original spare graphics board for old TDC3000 operator stations,matched with keyboard interface module,trackball module and LCN communication board to form a complete HMI console.

Key specifications：Plug-in board for TDC3000 operator station chassis,output RGB analog video and sync signals,proprietary interface with station CPU. Operating temperature range is 0°C to +60°C. It supports sync loss,video output failure and communication timeout fault diagnosis. The PCB is conformal coated for dust and moisture resistance,built-in EMC filter circuits reduce surge interference inside the console cabinet. Edge connector and test points are reserved for video signal measurement and image adjustment.

This display interface board is widely deployed in petrochemical,chemical,power generation and water treatment plants for legacy TDC3000 DCS operator station repair and renewal projects. It cooperates with Honeywell LCN adapter board,input HMI accessories and CRT monitor to realize process graphics display. As a core unit for display interface board and CRT video driver,it is the key graphics output hardware of TDC3000 operator console. Clearly defined video connectors simplify console wiring,image synchronization adjustment and periodic display quality verification work for control engineers.
