Product Overview

The Woodward 5501-471 (5501471) is an intelligent Serial Input/Output (SIO) module specifically engineered for the NetCon control platform. It serves as a high-speed communication bridge for supervisory control in distributed turbine and engine management networks. Driven by a 32-bit ARM Cortex processor, this module executes complex data translation between field devices and the main controller. It supports multiple serial standards and Modbus protocols, ensuring seamless integration in power generation and marine propulsion systems. We supply this unit as 100% Brand New and Original, complete with its signature 24-character alphanumeric LED matrix for instant local diagnostics.

Engineering Advantages

Multi-Protocol Versatility: The 5501-471 eliminates the need for external protocol converters. Ports 3 and 4 allow software configuration between RS-232, RS-422, and RS-485, enabling direct connection to a wide variety of PLCs, HMIs, and smart field instruments via Modbus RTU or ASCII.
Dual-Redundant Power Security: To prevent system failure during power fluctuations, the module accepts dual 24 VDC inputs. If the primary power rail fails, the secondary input maintains module operation, ensuring continuous data flow in critical turbine safety applications.
Real-Time Local Diagnostics: The integrated 24-character LED matrix provides immediate visibility into system status and port activity. This feature allows technicians to troubleshoot communication faults directly at the cabinet without connecting a laptop, significantly reducing Mean Time to Repair (MTTR).
High-Precision Signal Processing: Beyond serial data, the module handles 4–20 mA analog signals with ±0.1% accuracy and manages 20 discrete I/O points. This high-density I/O integration reduces the number of separate modules required in the NetCon rack, saving space and cost.
Extreme Thermal Endurance: Designed for the high-heat environments of engine rooms and offshore platforms, the 5501-471 operates reliably from –40 °C to +85 °C. The robust physical construction protects internal 32-bit electronics from vibration and thermal cycling.

FAQs

How do I configure the serial mode for Ports 3 and 4?You configure these ports through the Woodward NetCon software environment. The module supports software-selectable jumpers for RS-232, RS-422, or RS-485 (2-wire or 4-wire) modes, allowing you to match the electrical requirements of your specific field devices.

What are the relay output ratings for the 5501-471?The module features 8 relay outputs rated at 2 A each. These outputs are suitable for triggering external alarms, interlocks, or small solenoids directly from the SIO module based on Modbus commands or local logic.
