Woodward 5453-759 MicroNet-Plus Control System Chassis

Product Overview

The Woodward 5453-759 is a 14-slot MicroNet-Plus system chassis designed to serve as the central mounting and interconnection platform for Woodward digital control architectures. It provides mechanical support, regulated power distribution, and backplane communication for a full complement of MicroNet-Plus plug-in modules.

This chassis enables a fully modular control configuration, allowing CPUs, discrete and analog I/O, communication interfaces, and application-specific modules to operate within a single integrated frame. It is intended for continuous-duty operation in demanding turbine, engine, and generator control environments.

System Function and Architecture

As the foundational element of a MicroNet-Plus installation, the 5453-759 chassis delivers internally regulated 24 VDC power and distributes system buses across all module slots via a high-reliability backplane. Each slot supports hot-insertable MicroNet-Plus modules when standard ESD handling practices are observed.

The backplane is engineered to maintain signal integrity and deterministic communication between control processors and I/O subsystems, supporting real-time control strategies and safety-critical logic execution.

Frequently Asked Questions

Q: Is the 5453-759 compatible with standard MicroNet modules? A: No. This chassis is specifically designed for MicroNet-Plus modules and backplane architecture. It is not compatible with legacy MicroNet hardware.

Q: Can modules be replaced while the system is energized? A: The chassis supports hot-swappable modules when system design and safety procedures permit, and when proper ESD precautions are followed.

Q: Does the chassis include a power supply? A: No. The chassis distributes regulated 24 VDC but relies on an external system power supply.
