Product Description
Woodward 5503-282 MicroNet Analog I/O Module
Product Overview
- The Woodward 5503-282 is a MicroNet Analog Input/Output (I/O) Module designed for use in Woodward’s MicroNet control system, which controls industrial gas turbines, steam turbines, and compressors in applications such as power generation, oil and gas, and marine systems. This module provides high-precision analog signal interfacing, allowing the MicroNet system to monitor and control parameters like pressure, temperature, flow, or valve position. It features multiple analog inputs and outputs for integration with sensors, actuators, and other field devices. The 5503-282 is optimized for real-time data acquisition and control, with robust diagnostics for reliable operation in demanding environments. Compared to Woodward’s MicroNet CPU modules (e.g., 5501-381), power supply modules (e.g., 5501-432), or genset controllers (e.g., EasyGen-3200-5, 8440-2050E), the 5503-282 is a specialized I/O interface, not a control or power device. It is distinct from Woodward’s protection relays (e.g., XD1G11), servo position controllers (e.g., 8200-226), communication modules (e.g., SST-ESR2-CLX-RLL), excitation systems (e.g., DECS-100-B15), electronic governors (e.g., DYN1-10784-003-0-12), and actuators (e.g., 8408-921).
