Allen Bradley 1771-CP1 PLC 5 I/O Chassis Power Cable Assembly

Product Overview

The Allen Bradley 1771-CP1 functions as a specialized power cable assembly within the PLC 5 architecture. It provides the essential electrical link between a chassis-mounted 1771-P7 power supply and a panel-mounted I/O chassis. We supply this component as 100% Brand New, ensuring factory-spec conductivity and insulation integrity for critical control system power distribution.

Technical Specifications

The 1771-CP1 features high-grade materials designed to maintain stable power delivery across the 1771 backplane.

Engineering Advantages

• Optimized for Tight Enclosures: The 1.04-foot cable length eliminates excess slack within the control cabinet. This precise sizing prevents cable tangles and ensures clean routing between the power source and the I/O rack, maximizing airflow and thermal dissipation.

• Environmental Hardening: The assembly features a conformal coating. This protective layer repels moisture, dust, and corrosive airborne contaminants, preventing terminal oxidation and maintaining low-resistance connections in harsh refinery or chemical plant environments.

• Secure Mechanical Interface: The connectors facilitate a ruggedized physical lock between the power supply and the chassis. This design resists disconnection caused by the high-frequency vibrations typically associated with heavy industrial machinery.

• High-Efficiency Power Path: The internal conductors support up to 1.0 Amp of backplane current with minimal voltage drop. This ensures that logic-level voltages remain within tolerance, preventing "brown-out" resets of sensitive I/O modules during peak operation.

FAQs

• Can I use the 1771-CP1 with power supplies other than the 1771-P7?

  The 1771-CP1 specifically connects a chassis-mounted 1771-P7 power supply to a panel-mounted chassis. Using this cable with unauthorized power sources may result in incorrect pin-out alignments or electrical failure. Always verify your hardware mounting configuration before installation.

• Does the 1.04-foot length include the connector heads?

  Yes. The 0.32-meter measurement represents the total length of the assembly. This short distance design specifically caters to side-by-side mounting or stacked configurations within a standard industrial enclosure.

• What mounting style does this cable support?

  This cable facilitates the connection when you mount the power supply in a separate chassis from the I/O modules. It bridges the gap between the power output port of the P7 unit and the power input terminal of the 1771 universal chassis.

• Is the cable resistant to chemical exposure?

  The conformal coating provides an additional barrier against chemical vapors and humidity. While the cable resists standard industrial environments, you should always route it through conduit or protected raceways if it faces direct exposure to liquid solvents or corrosive drips.
