Woodward 5466-411 MicroNet Ethernet Communication Module

Overview

The 5466-411 Ethernet module is a dedicated communication interface engineered for Woodward MicroNet™ digital control platforms. It enables deterministic, high-speed Ethernet data transfer between the primary CPU chassis and distributed remote terminal (RTN) expansion chassis, supporting scalable and fault-tolerant control system architectures.

Designed for continuous operation in demanding industrial environments, this module plays a critical role in maintaining real-time data integrity across distributed control networks commonly used in turbine and power management systems.

Core Functionality

The 5466-411 module acts as a chassis-level Ethernet bridge, facilitating internal system communication rather than external plant networking. It is optimized for reliable CPU-to-remote chassis data exchange and is not intended to function as a general-purpose Ethernet switch or gateway.

Key operational capabilities include:

• Deterministic Ethernet communication within MicroNet and MicroNet Plus systems
• Stable data synchronization between controller CPUs and RTN expansion racks
• Status monitoring via onboard LED indicators for link and activity diagnostics
• Single RJ45 Ethernet interface designed for internal control network topology

Electrical Characteristics

• Module supply voltage: 5.0 VDC ±5% (supplied by MicroNet chassis backplane)
• Power consumption optimized for continuous operation
• Electrical isolation handled at system level within the MicroNet chassis

Note: Some distributor listings reference 110 VAC or 125 VDC; these values apply to the overall control system power input, not to the 5466-411 module itself.

Mechanical Specifications

• Form factor: Panel-mounted control module
• Ethernet interface: Single RJ45 port
• Status indicators: Integrated LEDs for communication state
• Dimensions: 95 × 105 × 100 mm
• Weight: 1.40 lbs

Compliance and Documentation

The 5466-411 is manufactured in accordance with multiple international marine and industrial standards, including ABS, CSA, CE (EMC), and LRS approvals.

Installation, handling precautions, and system integration guidelines are documented in Woodward Application Note 51192, which should be consulted prior to deployment.

Typical Applications

This Ethernet communication module is commonly installed in:

• MicroNet and MicroNet Plus turbine control systems
• Distributed gas and steam turbine control architectures
• Power generation and energy management platforms
• Control systems requiring deterministic CPU-to-remote rack communication

FAQ

Q: Is the 5466-411 used for external Ethernet networking?
A: No. This module is intended for internal MicroNet system communication between main CPU chassis and RTN expansion chassis only.

Q: Does the module require a separate power supply?
A: No. The module receives regulated 5 VDC directly from the MicroNet backplane.

Q: Can it be used outside MicroNet systems?
A: No. The 5466-411 is specifically designed for Woodward MicroNet and MicroNet Plus control platforms.
