Woodward 5466-1036 Digital RTN Remote Transceiver Module

Overview

The 5466-1036 is a Digital Remote Real-Time Network (RTN) Transceiver Module engineered for distributed control architectures within Woodward MicroNet and MicroNet Plus platforms. This module operates as a Remote Transceiver (Remote XCVR), enabling deterministic, low-latency communication between CPUs, I/O racks, and remote control nodes.

Designed for high-availability systems, the module plays a critical role in maintaining synchronized real-time data exchange in both standard and Triple Modular Redundant (TMR®) configurations.

Core Functionality

The 5466-1036 module acts as the real-time networking interface for MicroNet control systems. It supports redundant RTN topologies, ensuring continuous operation even during single-path or component failures. Deterministic data transmission is maintained across all connected control elements, making the module suitable for mission-critical turbine and engine control applications.

The integrated Ethernet interface supports both RTN traffic and general Ethernet communication, reducing infrastructure complexity while maintaining strict real-time performance.
