Product Overview

The Woodward 8200-188 operates as a high-precision digital control system specifically engineered for the regulation of single-valve or single-extraction steam turbines. This 100% Brand New and Original 505 series module integrates speed control, extraction control, and system protection into a single localized unit. It manages the turbine's primary steam inlet valves to maintain constant speed or load, even under volatile grid conditions or fluctuating process steam demands. By utilizing field-configurable software, the 8200-188 eliminates the need for custom programming, making it a universal standard for industrial power generation and mechanical drive applications.

Engineering Advantages

Deterministic Speed Regulation: The 8200-188 utilizes high-speed PID algorithms to monitor Magnetic Pickup (MPU) signals. It corrects speed deviations in milliseconds, preventing overspeed trips and mechanical stress during sudden load drops.
Menu-Driven Configuration: Unlike generic PLCs, the Woodward 505 architecture features a dedicated front-panel vacuum fluorescent display (VFD) and keypad. This allows engineers to configure parameters, set PID tunings, and view alarm history directly on the factory floor without a laptop.
Redundant Speed Sensing: The module supports dual-speed inputs with automatic switchover logic. If one MPU signal fails, the controller seamlessly transitions to the secondary sensor, preventing unnecessary turbine shutdowns and production losses.
Industrial Hardening: Woodward builds the 8200-188 to withstand the extreme electromagnetic interference (EMI) and high-temperature environments typical of steam turbine decks. The solid-state design ensures long-term calibration stability, reducing the frequency of periodic maintenance intervals.

FAQs

Can the 8200-188 replace older 505 models like the 9907-164?

While the 8200-188 belongs to the same 505 family, you must verify terminal wiring and software configuration. It provides improved processing speed and better display clarity compared to legacy units, but we recommend a review of your current I/O mapping before installation.

What is the standard lead time for this module?

We typically maintain a stock of 30 units with a lead time of 1–3 working days. We utilize FEDEX, DHL, and UPS for express global delivery to minimize your facility's downtime.

Does this unit support Modbus communication?

Yes. The 8200-188 includes dual serial ports that support Modbus RTU protocols. This allows you to integrate turbine data—such as speed, valve position, and alarms—directly into your plant-wide DCS or SCADA system.

How do I handle a "Module Fault" indicator?

First, check the 24 VDC power supply stability. If the fault persists, use the front-panel diagnostic menu to identify the specific error code. Most faults relate to MPU signal loss or configuration mismatches rather than internal hardware failure.

What's clients say about us

Excellent Emergency Support!

Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
