Product Overview

The Woodward 5501-470 serves as the primary non-volatile data repository for the MicroNet™ and MicroNet™ Plus digital control platforms. This high-reliability memory module safeguards critical configuration data, application program codes, and vital data logs against power loss or system resets. In the high-stakes environment of gas turbine and diesel engine management, the 5501-470 ensures that the control logic remains intact and immediately accessible for deterministic processing. By utilizing a robust architecture capable of withstanding extreme vibration and thermal shifts, this module provides the stability required for rotating machinery monitoring where high-speed data integrity is paramount for preventing overspeed conditions and mechanical failure.

Core Technical Advantages

The 5501-467 leverages the high-performance VMEbus interface, a standard in industrial computing known for its low-latency communication and high data throughput. This ensures that the CPU can retrieve application code and store fault logs without bottlenecking the system's real-time control loops.

Unlike standard commercial storage, this module features a true industrial-grade hardware design that handles up to 15 g of shock and operates in environments ranging from -40°C to +85°C. The flexibility of the 5501-470 allows for single, dual, or triple-board configurations, enabling engineers to scale the memory architecture based on the complexity of the turbine or compressor control algorithm. Its non-volatile nature means it requires no battery backup to maintain the 470 KB of data, eliminating a common point of failure found in lesser storage solutions and ensuring long-term operational readiness in remote power generation sites.

Technical Specifications

Installation & Engineering Guide

Precision handling is mandatory when installing the Woodward 5501-470 into a MicroNet chassis. Technicians must use a grounded ESD wrist strap to prevent electrostatic discharge from damaging the sensitive VMEbus circuitry. Before insertion, verify that the chassis power is completely off; hot-swapping memory modules can lead to data corruption or hardware damage.

Ensure the card aligners match the VMEbus slot rails perfectly. Once inserted, use the front-panel captive screws to secure the module into the chassis frame. This mechanical connection is vital, as it ensures the module maintains its 15 g shock rating. For configurations involving dual or triple-board setups, verify the addressing jumpers (if applicable) match the system’s memory map configuration to avoid resource conflicts within the MicroNet CPU environment.

Engineering Advantages

The 5501-470 is specifically hardened for the "Hot End" of industrial plants. Its resilience against 100% non-condensing humidity makes it the ideal choice for offshore platforms and coastal refineries where moisture is a constant threat. Because it integrates natively with the Woodward MicroNet ecosystem, it offers seamless compatibility with existing TSI (Turbo System Integrity) protocols. This allows for high-fidelity data logging of vibration and temperature parameters, ensuring that engineers have an accurate "black box" record of events leading up to any system trip or alarm.
