Woodward 5501-471 NetCon SIO Module

Product Introduction

The Woodward 5501-471 NetCon SIO Module is a Serial Input/Output (SIO) communication module designed for use within the Woodward NetCon™ and MicroNet™ digital control platforms. It serves as a communication interface, enabling reliable serial data exchange between the control system and external field devices such as programmable logic controllers (PLCs), sensors, actuators, and human-machine interfaces (HMIs).

Built for harsh industrial conditions, this module supports multiple serial communication protocols including RS-232 and RS-485, and can be configured to support Modbus RTU or ASCII for flexible integration. As part of the modular NetCon architecture, the 5501-471 allows engineers to extend communication capabilities without redesigning the core system.

The module is typically used in turbine, engine, and generator control systems where dependable communication is mission-critical. With rugged construction, redundancy support, and diagnostics capabilities, the 5501-471 enhances the reliability and interoperability of Woodward-based control solutions.
