Honeywell 51201298-290 Shielded Control Cable

Product Description

The Honeywell 51201298-290 shielded control cable is engineered for high-reliability signal transmission within Honeywell distributed control system architectures. Designed to support long-term operation in electrically noisy and mechanically demanding environments, this cable provides stable connectivity between controllers, I/O subsystems, and field instrumentation.

Optimized for Honeywell TDC 3000 and Experion PKS platforms, 51201298-290 combines high-purity copper conductors with dual-layer electromagnetic shielding to minimize signal degradation, cross-talk, and external interference. The cable construction supports consistent electrical performance across wide temperature ranges commonly encountered in process automation installations.

Technical Specifications

Key Technical Characteristics

Electromagnetic immunity is achieved through combined foil and braid shielding, significantly reducing susceptibility to EMI and RFI sources in control cabinets and plant wiring trays.

The copper conductor design ensures low resistance and stable impedance, supporting accurate analog and digital signal transmission over extended cable runs.

The flame-retardant jacket and robust insulation system provide mechanical durability, thermal resistance, and compliance with industrial safety standards.

Cable flexibility allows routing through dense control panels and structured wiring systems without compromising shielding effectiveness.

Application Scenarios

This cable is commonly deployed in control rooms, marshalling cabinets, and field wiring networks where signal integrity is critical. Typical use cases include interconnection of I/O modules, controller racks, remote termination assemblies, and field devices within Honeywell DCS installations.

It is particularly suitable for environments with variable temperatures, high electrical noise, and continuous operation requirements such as chemical processing, power generation, refining, and manufacturing facilities.

Installation & Engineering Considerations

Proper grounding of the cable shield at designated termination points is essential to achieve optimal noise suppression.

Bend radius and mechanical strain limits should be respected during installation to maintain conductor and shield integrity.

While electrically compatible with many control systems, this cable is dimensioned and specified primarily for Honeywell platforms and may not be mechanically interchangeable with non-Honeywell cable assemblies.

Frequently Asked Questions

Q: Is the 51201298-290 suitable for both analog and digital signals?
