The Allen-Bradley 1756-A13 is a 13-slot chassis designed for the ControlLogix automation platform. It serves as the physical housing and backplane for ControlLogix controllers, communication adapters, and I/O modules. The chassis provides the necessary power distribution and high-speed communication bus required for module operation within a ControlLogix system.

Features

  • Thirteen (13) dedicated slots for module installation.
  • Supports Removal and Insertion Under Power (RIUP), allowing for module replacement without shutting down the entire system.
  • Integrated backplane for power distribution and inter-module communication.
  • Supports producer/consumer communication and system-wide time stamping.
  • Robust design for panel-mount installation in NEMA-rated enclosures.

Applications

This chassis is suitable for demanding industrial environments, including:

  • Energy and power generation, such as turbine control and auxiliary systems.
  • Oil and gas production, including refinery and chemical plant automation.
  • Infrastructure projects, such as tunnel ventilation and airport baggage handling systems.
  • Food, beverage, and pharmaceutical manufacturing requiring precise production control.

Installation Guidelines

  • Ensure the chassis is mounted on a flat, rigid surface within a NEMA-rated enclosure.
  • Maintain adequate clearance around the chassis to facilitate heat dissipation and airflow.
  • Use all eight mounting tabs to secure the chassis firmly to the backplane.
  • Ensure the system is properly grounded according to local electrical codes to minimize EMI/RFI interference.
  • Always power down the system before installing or removing the chassis itself, though individual modules support RIUP.
  • Verify that the power supply module is correctly seated in the designated slot to ensure proper backplane voltage distribution.
