Product Details：

Honeywell 51201420002 (51201420-002) is a pre-terminated flat ribbon cable assembly dedicated for Honeywell TDC3000 legacy DCS IOP system,used for the parallel signal connection between 51201420001 FTA termination assembly and the plug-in IOP module installed on the five-slot IOP chassis. This cable transmits multi-channel analog 4-20mA current signals and digital dry contact signals between the I/O processor board and field terminal FTA board,strictly matching the channel definition and signal pin sequence of TDC3000 IOP interface. It adopts multi-conductor flat cable structure with insulation layer that can resist oil,aging and mechanical abrasion,adding internal shielding design to reduce crosstalk between adjacent signal channels in heavy industrial cabinet environment and avoid signal distortion or channel interference. Both ends are pre-fitted with matched IDC connectors,plug and play directly without manual crimping or wire sorting,greatly reducing wiring error risk during cabinet reconstruction,IOP and FTA spare replacement. It is the matched interconnection cable for analog input module,mixed I/O control module and corresponding FTA terminal board. When the original ribbon cable is aging,damaged or insufficient length,replacing this cable can restore the signal transmission path between IOP board and field wiring terminals. It is a commonly stocked spare wiring accessory for old TDC3000 projects,matched with 51197020100 analog input board,51197018100 I/O control board and five-slot IOP chassis power supply.

Key specifications：Pre-assembled multi-channel flat ribbon cable for TDC3000 IOP-FTA connection,IDC connectors at both ends,channel pin definition consistent with TDC3000 IOP standard. Operating temperature range is 0°C to +60°C. It supports continuity test and channel isolation check during maintenance troubleshooting.

This FTA ribbon cable is widely deployed in petrochemical,chemical,power generation and water treatment plants for legacy TDC3000 DCS I/O cabinet wiring modification,channel expansion and spare replacement projects. It cooperates with Honeywell CE dual-node processor,NIM gateway and HM history module to build complete Data Hiway field signal acquisition control architecture. As a core unit for FTA ribbon cable and IOP interconnection harness,it is the key multi-channel signal transmission medium between TDC3000 IOP module and field termination board. Clearly marked pin sequence labels simplify cable installation,channel calibration test and regular insulation aging inspection work for control engineers.
