MOTOROLA AET-3047  Industrial Automation Mounting Frame

MOTOROLA AET-3047  Industrial Automation Mounting Frame

Introduction

The MOTOROLA AET-3047 is a specialized hardware component within the Motorola industrial control and VMEbus ecosystem.

Often referred to in technical catalogs as a Mounting Frame or Chassis Component,

the AET-3047 provides the structural housing and mechanical interface for VME-series modules, power supplies, and backplane assemblies.

It is engineered to ensure high-precision alignment of high-density connectors, protecting sensitive electronic modules from mechanical stress and thermal buildup in rugged industrial environments.

Related Models

The AET-3047 is often found integrated into or used alongside these Motorola assemblies:

MVME110-001: A VME module frequently housed within this frame series.

W3047B01A: A related internal board assembly often cross-referenced with this frame.

MVME705A: Transceiver I/O modules that dock into AET-series frames.

AET-3048: A wider-capacity version of the mounting chassis.

Application Cases

Distributed Control Systems (DCS): Provides the physical housing for CPU and I/O modules in power plants and chemical processing facilities.

Legacy System Maintenance: A critical structural replacement part for aging Motorola PLC systems where original frames have suffered environmental corrosion.

Military Simulation: Used in grounded flight simulators where VME-based racks require secure, vibration-resistant module mounting.

Signal Processing: Acts as the sub-rack frame for high-speed data acquisition boards in radar and communication hubs.

Product Advantages and Features

Precision Alignment: Guaranteed tolerance levels for VME P1/P2 connector mating, reducing the risk of pin damage during module insertion.

EMI/RFI Shielding: The metallic construction acts as a Faraday cage, protecting internal logic boards from electromagnetic interference common in factory settings.

Rugged Longevity: Unlike plastic-heavy modern frames, the AET-3047 is built for 20+ years of continuous service in high-vibration and high-temperature areas.

Modular Versatility: Designed to be easily incorporated into standard 19-inch industrial racks.

Other Models in the Same Series

AET-3045: Compact single-slot mounting kit.

MVME Series: The primary line of processor and I/O boards that occupy these frames.

MVME900 Series: Large-scale chassis systems that utilize AET-series internal components.

Installation and Maintenance

Installation: Ensure the mounting surface or rack rails are level. Use standard M3 or M4 screws to secure the AET-3047 frame.

When sliding in electronic modules, ensure they track correctly along the guide rails before applying pressure to seat the connectors.

Inspection: Periodically check the guide rails for wear or debris which could cause module misalignment.

Grounding: It is vital to connect the frame’s grounding lug to the main system ground to ensure effective EMI shielding and user safety.

Maintenance: No active electronic maintenance is required for the frame itself,

but the backplane connectors (if attached) should be cleaned with compressed air to prevent dust-induced shorts.

Unique Product Description

The Motorola AET-3047 is the “skeletal system” for high-reliability industrial computing.

While the processor modules get the attention, the AET-3047 provides the structural integrity and precision necessary for those modules to function.

Its heavy-duty aluminum design and revision-controlled manufacturing make it a preferred choice for engineers who cannot afford mechanical failure in their control racks.

When maintaining a legacy Motorola system, the AET-3047 is the essential foundation for a stable and secure hardware environment.
