Product Details：

Honeywell 51191578100 (51191578-100) is a dedicated IR touch screen connection cable for Honeywell TDC3000 legacy DCS operator station,its main purpose is stable signal transmission between infrared touch frame assembly and operator station main control board. This special harness matches the 51191573100 infrared touchscreen module,transmitting the infrared coordinate scanning signal and power supply signal of the touch frame to the console mainboard,realizing touch position recognition and command upload. It adopts multi-core shielded wire structure to suppress electromagnetic interference inside the control cabinet,preventing touch coordinate drift,miss-trigger and touch failure caused by nearby power supply and communication signal interference. Both ends are pre-terminated with dedicated plug connectors,directly plug and play without on-site wiring and soldering,greatly reducing the risk of poor contact during station maintenance and touch screen replacement. It has wear-resistant and flexible outer sheath,adapted to frequent disassembly of the operator station front panel. It defines fixed pin assignment for power,transmitter and receiver signal lines. Engineers can quickly check continuity with a multimeter during fault troubleshooting. It is a scarce original spare HMI cable accessory for old TDC3000 projects. When the original touch cable is aging,broken or the insulation layer is damaged,this cable can restore the touch operation function of the operator console.

Key specifications：Pre-assembled shielded multi-core cable,dedicated matching for TDC3000 IR touch frame,pre-molded connectors at both ends. Operating temperature range is 0°C to +60°C. It supports continuity and short circuit inspection. The inner core wire adopts anti-oxidation conductor,stable signal transmission for long-term continuous operation.

This IR touch screen cable is widely deployed in petrochemical,chemical,power generation and water treatment plants for legacy TDC3000 DCS operator station renovation and spare replacement projects. It cooperates with Honeywell IR touch frame,operator station mainboard and display unit to complete touch human-machine interaction. As a core unit for touch screen cable and touch frame harness,it is the necessary signal transmission medium for TDC3000 infrared touch assembly. Clearly marked connector pins simplify wiring,touch calibration and periodic cable aging inspection work for control engineers.
