Description

The Allen-Bradley 1756-M14 is a specialized internal expansion memory module designed for the ControlLogix automation platform. By utilizing high-speed Dynamic Random Access Memory (DRAM), this module provides the necessary volatile memory extension to support larger control programs, complex instruction sets, and expanded data arrays. It is engineered for seamless integration into standard ControlLogix chassis architectures, allowing for system scalability without the need for a full processor replacement.

Features

  • High-density DRAM architecture for low-latency data access.
  • Compact, single-slot design for efficient chassis utilization.
  • Ultra-low power consumption, minimizing thermal output within the enclosure.
  • Robust electrical noise filtering and surge protection.
  • Designed for high-vibration and high-shock industrial environments.

Applications

This module is ideal for industrial environments requiring increased memory capacity for distributed control networks, high-speed assembly line automation, and complex process loops where standard processor memory limits may be reached.

Installation Guidelines

  • Ensure the ControlLogix chassis power is disconnected before installing or removing the module.
  • Handle the module by the edges to prevent electrostatic discharge (ESD) damage to sensitive components.
  • Align the module carefully with the chassis guide rails and ensure it is fully seated in the backplane connector.
  • Secure the module using the top and bottom latching mechanisms to ensure proper grounding and vibration resistance.
  • Verify that the module is not installed in an environment exceeding the specified temperature or humidity ranges.

FAQ

Does this module require external power? No, the 1756-M14 draws all required power directly from the ControlLogix chassis backplane.

Is this module compatible with all ControlLogix processors? The 1756-M14 is designed for the ControlLogix platform; please verify your specific processor firmware and hardware revision compatibility in the official Allen-Bradley technical documentation.
