Description
Woodward 5466-425D
Technical Specifications
- Product Family: MicroNet Digital Control.
- Role: High-Density Analog I/O Module.
- Channels: Features up to 34 analog inputs, with 24 configurable between 4-20mA or thermocouple inputs, and 10 configurable for 4-20mA or RTD inputs.
- Update Time: Fast 5 ms update rate for real-time responsiveness.
- Cold Junction Inputs: Includes 2 dedicated cold junction inputs for accurate temperature compensation.
Functional Features
- Versatile Signal Support: Handles a wide range of input signals including voltage, current, temperature, and pressure.
- Advanced Signal Conditioning: Built-in amplification and filtering ensure high-precision signal processing.
- Self-Diagnostics: Automatically tests itself via the CPU after a board reset; an LED blinks to indicate specific fault types.
- Space Efficiency: High channel capacity in a compact design maximizes control cabinet space utilization.
Application Scenarios
Ideal for critical control applications in power generation, manufacturing, and energy management where precise monitoring of analog parameters is required. It is particularly vital for TMR (Triple Modular Redundancy) system types.
Performance Parameters
- Operating Temperature: Withstands extreme environments from -40°C to +85°C.
- Power Consumption: Low power draw of approximately 10W.
- RTD Source Current: Provides a stable 1 mA source current for RTD measurements.
Material Composition
Constructed with high-quality industrial-grade materials and internal components that are well-protected against harsh conditions. The PCB features conformal coating for resistance against moisture and corrosion.
Structural Characteristics
Designed for installation via control chassis card guides and is securely held in place by several screws. Features a single diagnostic LED on the front panel for quick visual status checks.
Working Principle
The module acquires analog signals from field sensors, conditions and filters them, and converts them into digital data for the main MicroNet controller. It also receives digital commands to drive analog outputs, maintaining a continuous closed-loop control process.
Installation Requirements
Insert the module into the designated slot in the MicroNet chassis, ensuring it slides smoothly along the card guides. Secure the module using the provided retaining screws to prevent vibration-induced disconnection.
Usage Precautions
- Ensure the configuration of the 24 selectable inputs matches the connected field devices.
- Observe Electrostatic Discharge (ESD) precautions when handling the module.
- Refer to the LED blink codes in the manual (26166V1) for accurate fault diagnosis.
