The WOODWARD 5466-326 is an 8-channel Analog Input Module designed for use with Woodward’s MicroNet Digital Control Series (including MicroNet Plus and often compatible with MicroNet TMR systems). It provides a crucial interface for acquiring various analog signals from field sensors, such as 4-20 mA current loops or 0-5 Vdc voltage signals, and converting them into digital data that the control system can process. This allows for precise monitoring and control of machinery and industrial processes.

• Product Type: Analog Input Module
• Manufacturer: Woodward
• Series: MicroNet Digital Control (MicroNet Plus, MicroNet TMR)
• Channels: 8 channels
• Input Types: Analog current (e.g., 4-20 mA) and/or voltage (e.g., 0-5 Vdc, 0-10 Vdc)
• Function: Converts analog sensor signals to digital data for the control system.

3. Detailed Product Description:

In industrial automation, the ability to accurately measure and interpret real-world physical parameters is fundamental to effective control. The WOODWARD 5466-326 serves this exact purpose within the Woodward MicroNet control system.

The 5466-326 is an 8-channel Analog Input Module that slots into a MicroNet chassis. Each of its eight independent channels can be configured to accept standard analog signals. While the exact range depends on the specific variant and configuration, these typically include:

• Current Inputs: Such as the widely used 4-20 mA current loop, which is robust against noise and signal loss over long distances.
• Voltage Inputs: Such as 0-5 Vdc or 0-10 Vdc.

This module provides the necessary signal conditioning, filtering, and analog-to-digital conversion to transform the raw sensor data into a format usable by the MicroNet CPU. This digital data is then integrated into the control logic, allowing the system to:

• Monitor Process Variables: Continuously track parameters like temperature, pressure, flow rate, liquid levels, and more.
• Implement Control Algorithms: Use the input data for closed-loop control, for example, adjusting a valve based on a pressure reading.
• Generate Alarms and Trips: Trigger alerts or protective shutdowns if process variables exceed predefined safe operating limits.
• Provide Data for Diagnostics and Trending: Log historical data for performance analysis and predictive maintenance.

The 5466-326 is designed for high reliability and accuracy in harsh industrial environments. It typically offers electrical isolation between channels and from ground, which is crucial for preventing ground loops and protecting the control system from electrical noise or faults in the field wiring.

Like many newer Woodward modules, it’s often a “no-potentiometer, no-calibration” design. This simplifies installation and replacement, as no manual adjustments are needed, reducing maintenance time and potential human error. It supports automatic module detection, meaning the CPU can identify the module’s presence and type, further streamlining setup.

Key Features and Benefits:

• 8 Independent Analog Input Channels: Provides a high density of inputs for comprehensive process monitoring.
• Versatile Signal Acceptance: Supports common industrial analog signals like 4-20 mA and various voltage ranges.
• High Accuracy and Resolution: Delivers precise measurements for critical control and protection functions.
• Electrical Isolation: Protects the control system from field wiring issues and improves signal integrity.
• No Calibration/Adjustment Required: Simplifies installation, maintenance, and module replacement.
• Automatic Module Detection: Streamlines system setup and configuration.
• Robust Industrial Design: Built to withstand demanding industrial environments, ensuring long-term reliability.
• Broad Compatibility: Integrates seamlessly with MicroNet Plus and MicroNet TMR control systems.

Technical Specifications (General, as precise details can vary slightly by sub-variant or manual version):

Typical Applications:

The WOODWARD 5466-326 is essential in a wide range of industrial applications where continuous and accurate monitoring of analog process variables is critical for control, efficiency, and safety.

• Power Generation: Monitoring temperatures (e.g., bearing, exhaust), pressures (e.g., fuel, lube oil), and flows (e.g., fuel flow, cooling water) on gas turbines, steam turbines, and generators.
• Oil and Gas Industry: Measuring various pressures, temperatures, and levels on compressors, pumps, and processing equipment.
• Petrochemical and Chemical Plants: Monitoring process variables in reactors, distillation columns, and other chemical processes.
• General Industrial Automation: Any application involving the precise measurement of analog signals from field instrumentation for control and alarming.
