6G Controls - Leading Supplier of New & Original PLC 、DCS Parts and Automation Controller
Product Description
The Woodward 8200-1331 is an industrial electronic control and I/O interface module developed for high-availability turbine, engine, and generator control systems. Designed within the Micronet / Netcon architecture, this module provides deterministic real-time signal acquisition, conditioning, and communication between field instrumentation and Micronet control processors.
Engineered for continuous operation in harsh environments, 8200-1331 integrates analog and discrete I/O handling, embedded diagnostics, and multi-protocol communications. Depending on system configuration, it may also be integrated with local display and keypad interfaces for commissioning, monitoring, and parameter adjustment.
While some distributors associate this unit with HMI-centric solutions, its primary function remains high-speed control I/O within distributed Woodward control platforms.
Core Control Architecture
The 8200-1331 is built around a real-time 32-bit control processor optimized for deterministic execution. Control tasks are processed in fixed execution cycles to ensure predictable response in critical speed, load, and protection loops.
Typical control scan times are on the order of milliseconds, enabling precise regulation of turbines, generators, and auxiliary systems where timing accuracy is essential.
Input / Output Capabilities
This module supports mixed-signal processing for both continuous and discrete field signals commonly found in rotating equipment control systems.
Analog input channels support industry-standard current loops with high-resolution conversion suitable for pressure, temperature, speed, and position feedback. Analog outputs provide stable current drive for actuators and control elements.
Discrete I/O points are configurable for monitoring contacts, alarms, and command signals, allowing flexible adaptation to different plant architectures.
Human-Machine Interface & Local Operation
In certain Micronet configurations, 8200-1331 supports an integrated color display with keypad navigation. This interface allows operators and commissioning engineers to view system status, adjust parameters, and perform diagnostics without requiring external programming tools.
HMI functionality is configuration-dependent and typically implemented as part of a broader control panel or controller assembly.
Communication & Networking
The module supports multiple industrial communication standards to ensure seamless integration with supervisory systems, remote I/O, and plant networks. Ethernet connectivity enables high-speed data exchange using widely adopted industrial protocols, while serial and CAN-based interfaces support deterministic fieldbus communication in distributed control environments.
Power Supply & Environmental Ratings
Designed for low-voltage DC control cabinets, 8200-1331 operates from a wide 24 VDC input range and maintains stable performance under electrical and thermal stress. Its extended operating temperature range makes it suitable for both enclosed panels and demanding industrial locations.

FAQ
Is the 8200-1331 a standalone controller?
No. It functions as an I/O and interface module within a Micronet or Netcon control system and requires a compatible CPU for control logic execution.
Does it always include an HMI display?
HMI capability depends on system configuration. Some installations integrate local display and keypad functionality, while others use external operator stations.
Is the module suitable for safety-critical applications?
Yes. It is designed for mission-critical control environments where deterministic timing, diagnostics, and reliability are required.
