Technical Overview

The 5466-330 (5466-330) is a precision-engineered Analog Input/Output module developed for the Woodward MicroNet and NetCon control architectures. This high-density component is designed to bridge the gap between complex digital control logic and analog field instrumentation. With advanced Digital-to-Analog (D/A) conversion technology, the 5466-330 (5466-330) provides the high-resolution signal reproduction necessary for the finite positioning of actuators, fuel valves, and guide vanes in turbine and engine management systems.

Detailed Technical Specifications

The following performance metrics define the signal integrity and thermal stability of the 5466-330 (5466-330):

• Module Architecture: High-density analog signal processor for chassis-integrated control.

• Full-Scale Output Range: Optimized for standard 0–25 mA industrial loops.

• Signal Resolution: High-resolution D/A conversion for smooth, continuous control curves.

• Readback Accuracy: $\pm 0.5\%$ of the 0–25 mA full-scale range (ensures internal loop validation).

• Thermal Stability:

• Maximum Output Temperature Drift: 125 ppm/°C.

• Maximum Readback Temperature Drift: 400 ppm/°C.

• Hardware Interface:

• Standard card-guide chassis mounting for secure vibration resistance.

• High-density connector interface designed for multi-core shielded analog cabling.

• Communication Compatibility: Seamlessly integrates with Woodward CPUs via the proprietary high-speed backplane for PLC and DCS handshaking.

• Industrial Hardening: Hardened circuitry to mitigate electromagnetic interference (EMI) and signal noise.

Application & System Reliability

The 5466-330 (5466-330) is an essential upgrade for facilities requiring tighter process tolerances. By utilizing the onboard readback circuitry, the module can self-verify its output signals, providing an extra layer of diagnostic security in "triple modular redundant" (TMR) or simplex control setups. Its robust mechanical design ensures that once seated in the chassis, electrical connections remain stable even in high-vibration power generation environments.
