1756-A17/C Allen-Bradley PLC Programmable Logic Controller 330 MA 100W 125V

1756-A17/C Description

1756-A17/C Features

• High-Speed Backplane:​ Features a high-integrity, multi-drop parallel backplane that supports high-speed deterministic data exchange (up to 2 Gigabit internal bandwidth) between the controller, I/O modules, and communication modules with precise synchronization.
• Scalable and Modular Architecture:​ The 17-slot design provides extensive capacity for building large, complex control systems in a single chassis, reducing the need for multiple racks and simplifying system architecture.
• Redundant Power Supply Capability:​ Designed to support the use of redundant 1756 power supplies for mission-critical applications requiring maximum uptime. The chassis can accept two power supplies, with automatic switchover in case of a primary supply failure.
• Robust Construction and Cooling:​ Built with a heavy-duty metal frame and includes an integrated, high-performance cooling fan assembly to ensure optimal operating temperatures for all installed modules, enhancing system reliability and longevity.
• Integrated Diagnostics:​ Includes status indicators (LEDs) for chassis power, backplane health, and slot activity, facilitating rapid system diagnostics and troubleshooting.
• Seamless Integration:​ Fully compatible with the entire ControlLogix ecosystem, including Logix 5000 controllers, 1756 I/O modules, and a wide array of communication adapters for networking (EtherNet/IP, ControlNet, DeviceNet, etc.).

1756-A17/C Materials & Application

• Primary Materials:
  • Chassis Frame:​ Constructed from cold-rolled steel with a corrosion-resistant finish for durability in industrial environments.
  • Backplane:​ A multi-layer printed circuit board (PCB) with gold-plated connectors, high-speed traces, and advanced signal integrity design.
  • Cooling System:​ Includes a ball-bearing fan and an aluminum heat sink structure for efficient thermal management.
  • Slot Guards:​ Metal or plastic slot fillers (provided) for covering unused slots to maintain proper airflow and IP rating.
• Primary Applications:
  • Centralized Machine Control:​ As the main control rack for large, complex machinery like stamping presses, assembly lines, or packaging systems.
  • Process Automation:​ Serving as the main controller chassis for batch processing, continuous flow control, and supervisory control in industries like chemicals, oil & gas, and pharmaceuticals.
  • Discrete Manufacturing:​ The core of control systems for automotive body shops, paint shops, and final assembly.
  • Large-Scale Material Handling:​ Controlling sortation systems, automated storage and retrieval systems (AS/RS), and warehouse logistics.
  • High-Availability/Redundant Systems:​ Used as the chassis for systems configured with redundant controllers and power supplies.
