Product Details：

Honeywell 51201420025 (51201420-025, MU-KFTA25) is a 25-meter pre-terminated flat ribbon cable assembly for Honeywell TDC3000 legacy DCS IOP and FTA termination assembly interconnection. It is an extra-long customized length option in this FTA cable series,used for scenarios where the five-slot IOP chassis and FTA terminal board are installed in separate cabinets with a long span distance. This cable strictly follows the TDC3000 IOP pin definition and fixed channel sequence,responsible for bidirectional transmission of standard 4-20mA analog current loop signals and dry contact digital input and output signals between plug-in IOP modules and field termination FTA board. It adopts multi-conductor insulated flat cable with reinforced shielding structure, which effectively suppresses long-distance signal attenuation and crosstalk between adjacent channels,prevents measurement jitter and signal distortion caused by electromagnetic interference from high-power frequency conversion equipment and power cables on site. Both ends are pre-fitted with matched IDC crimp connectors,ready for direct plug-in connection without on-site wire sorting and crimping work,greatly reducing wiring error risk during system reconstruction,cabinet separation transformation and spare replacement. It is compatible with analog input module,mixed I/O control module and the matched 51201420001 FTA termination assembly. When shorter cables cannot meet the long-span wiring requirement or the old cable insulation is aged and cracked,this 25m FTA ribbon cable can rebuild the stable signal transmission channel of the I/O subsystem. It is a special long-length spare wiring accessory for old TDC3000 projects,matched with 51197020100 analog input module,51197018100 I/O control module and five-slot IOP chassis power supply.

Key specifications：25-meter pre-assembled FTA flat ribbon cable for TDC3000 IOP-FTA connection,standard IDC connectors at both ends,pin sequence consistent with TDC3000 IOP specification. Operating temperature range is 0°C to +60°C. It supports continuity test and channel isolation inspection during maintenance troubleshooting.

This FTA ribbon cable is widely deployed in petrochemical,chemical,power generation and water treatment plants for legacy TDC3000 DCS split cabinet transformation,ultra-long-distance remote FTA wiring and spare stocking 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 25m FTA ribbon cable and extra-long IOP harness,it is the ultra-long special signal transmission cable for TDC3000 IOP and FTA interconnection. Clearly marked pin sequence labels simplify cable installation,channel calibration test and regular insulation aging inspection work for control engineers.
