The 1771-NC6 is a fully shielded interconnect cable within the PLC-5 system architecture. It has a physical length of 6 feet (1.8 meters) and features multi-pin hardware connectors on both ends. This cable functions to establish a direct point-to-point connection between 1771-N series high-resolution isolated analog I/O modules and compatible Remote Termination Panels (RTPs), enabling the transmission of current or voltage signals from field instruments to the PLC rack.
Continuous Signal Shielding
Pre-fabricated Errors Reduction
Mechanical Sliding Locking Mechanism
The Allen Bradley 1771-NC6 is a pre-fabricated, point-to-point interconnect cable belonging to the PLC-5 system architecture. Its exclusive function is to establish a hardwired electrical link between 1771-N Series high-resolution isolated analog input/output modules and external 1771 Remote Termination Panels (RTPs). Both ends of the cable assembly are fitted with heavy-duty 25-pin D-shell multi-pin connectors.
Each connector features an integrated mechanical sliding locking bar mechanism to secure the physical mating connection onto the front interface of the I/O module and the RTP board receiver slot. Constructed with internal multi-conductor twisted-pair copper wiring enclosed within an overall tinned copper braid and foil shield layer, terminated to the connector shells to maintain continuous ground continuity and provide a physical barrier against high-frequency electromagnetic interference (EMI).

Oil & Gas Exploration and Production
Used on onshore oilfields and offshore drilling platforms to connect RTPs with high-precision analog modules for accurately collecting strata wellhead pressure and crude oil temperature transmitter signals.
Petrochemical & Refining
Connects thermocouple compensation wires and analog modules in petrochemical hydrocracking and distillation tower units to perform extremely strict process temperature control.
Thermal Power Generation
Transmits critical high-resolution analog feedback signals such as superheated steam pressure, bearing vibration, and rotational speed in large boiler control systems and steam turbine monitoring.
Metallurgy & Iron and Steel Industry
Used inside control cabinets for blast furnaces, converters, and hot rolling mills to ensure stable transmission of molten steel temperature and hydraulic motor flow signals under heavy electromagnetic interference.
Water & Wastewater Treatment
Transmits remote water pH value, dissolved oxygen, and precise flow transmitter data used for pump group speed interlock control in large water purification plants and aeration tanks.
Pharmaceuticals & Biotechnology
Used in fermentation tanks and sterile preparation workshops to connect RTD sensors to high-resolution analog modules for strictly controlling temperature deviations within process formulas.
When using the Allen-Bradley 1771-NC6 cable, ensure both 25-pin D-shell connectors are fully seated and that you manually slide the mechanical locking bars to prevent signal loss from cabinet vibration. To prevent signal degradation, maintain the continuous integrity of the dual-layer shielding and avoid routing the cable adjacent to high-voltage AC power lines to minimize electromagnetic interference.
Additionally, map your channel densities correctly by deploying one cable for 4-channel N-series modules and two cables for 8-channel modules. Since this product was discontinued in 2021, practice careful handling during maintenance to avoid physical stress on the aging wire connectors.
The Allen-Bradley 1771-NC6 is a passive, shielded 6-ft cable with 25-pin D-shell connectors that routes analog signals between 1771-N Series modules and Remote Termination Panels. Discontinued in 2021, it is used for maintenance support.
The 1771-NC6 is a 6-foot (1.8-meter) fully shielded multi-conductor physical interconnect cable belonging to the Allen-Bradley PLC-5 control system architecture.
What is the primary purpose of the 1771-NC6?
Its exclusive purpose is to establish a hardwired physical electrical connection between 1771-N Series high-resolution analog I/O modules and external Remote Termination Panels (RTPs).
How is the 1771-NC6 cable used?
To use it, plug the 25-pin D-shell connector on one end of the cable into the front slot of the 1771-N Series module, insert the other end into the compatible Remote Termination Panel (RTP) slot, and manually engage the mechanical sliding locking bars on both ends.
Which PLC modules are compatible with the 1771-NC6?
The cable is directly compatible with Allen-Bradley 1771-N Series analog hardware, including the 1771-NB, 1771-NIV, 1771-NIS, and 1771-NOC modules, as well as the 1771-TCM temperature control module.
Which termination panels can connect to the 1771-NC6?
The remote end of the cable physically plugs into Rockwell-designated remote termination bases, such as the 1771-RTP1, 1771-RTP3, 1771-RTP4, and 1492-RTP4.
