1756-A17/B Allen-Bradley PLC Programmable Logic Controller DC 20.4-28.8V DC

1756-A17/B Description

The 1756-A17/B is a 17‑slot modular chassis for the Allen‑Bradley ControlLogix® and GuardLogix® control system platform. It provides the physical and electrical backbone, housing the system's power supply, controller(s), communication modules, and I/O modules. The "/B" revision indicates the latest manufacturing version, incorporating design improvements for enhanced grounding and compatibility. This chassis delivers robust power distribution, controlled communication via a high‑speed backplane, and superior mechanical stability, forming the essential foundation for building scalable, high‑performance, and mission‑critical industrial automation systems.

1756-A17/B Features

High‑Slot Capacity: The 17‑slot configuration offers maximum density for large, complex control systems, allowing the integration of multiple controllers, network bridges, and extensive I/O and specialty modules in a single, centralized enclosure.
High‑Speed Deterministic Backplane: Features a high‑performance, proprietary backplane that provides deterministic, high‑speed data exchange (up to several gigabits/sec) between all installed modules, ensuring reliable and synchronized system performance.
Dual Power Supply Slots: Includes two dedicated slots for redundant 1756 power supplies. This allows for hot‑backup power configurations, a critical feature for increasing system availability and uptime in continuous‑process or high‑value manufacturing applications.
Superior Mechanical Design: Constructed with a heavy‑gauge steel frame for exceptional rigidity, vibration resistance, and EMI/RFI shielding. The design facilitates optimal airflow for cooling and ensures secure module retention.
Enhanced Grounding & Compatibility: The "/B" revision model includes improved grounding features for better electrical noise immunity and is designed for full compatibility with the latest ControlLogix 5580 and 5570 series controllers and all 1756 I/O and communication modules.
Easy Installation & Maintenance: Features a removable backplane connector and clearly labeled slot numbers for straightforward module installation, removal, and system troubleshooting.

1756-A17/B Material & Applications

Material: The chassis structure is constructed from heavy‑gauge cold‑rolled steel with a corrosion‑resistant finish. The backplane is a multi‑layer printed circuit board (PCB) with high‑quality connectors and robust power distribution circuits. The card guides and module retainers are made of durable industrial plastics.
Applications: Used as the central hardware platform for building large‑scale control systems across industries. Typical applications include automotive final assembly plants, large material handling and distribution centers, major process industry facilities (oil & gas, chemical, pharmaceutical), and complex machine control lines requiring high I/O count, network diversity, and controller redundancy.
