Woodward Unit 9907-164 from 505 Digital microprocessor-based Controllers for Steam Turbines with Single or Split-Range Actuators.
FUNCTIONAL DESCRIPTION:
9907-164 is a Digital Microprocessor Controller Module manufactured and designed by Woodward. 505 Digital microprocessor-based Controllers for Steam Turbines with Single or Split-Range Actuators. It is an electronic device that receives inputs, processes them using an embedded microprocessor, and produces outputs to control a system or process. Digital controllers are widely used in industrial control systems, such as in manufacturing, chemical processing, and power generation. The digital controller typically includes several components, including a microprocessor, memory, input/output interfaces, and software. The microprocessor is responsible for executing software instructions to control the system or process, while memory stores the software program and data. The input/output interfaces allow the controller to receive and transmit signals to the system being controlled.
A digital microprocessor controller module, also known as a digital controller module or simply a controller module, is an electronic device that utilizes a microprocessor to control and monitor various functions and processes in a system. It acts as the central brain or control unit, receiving input signals, processing them, and providing output signals to control the system’s behavior. Controller modules are commonly used in a wide range of applications, including industrial automation, robotics, automotive systems, aerospace, consumer electronics, and more. They play a crucial role in ensuring precise and accurate control over complex systems.
The device listed here is the 9907-164 model, a part of the 505 and 505E Microprocessor-based governor control units. These control modules were designed specifically to operate steam turbines, as well as turbogenerators and turboexpander modules. The 505/505E series was developed, produced, and manufactured originally by Woodward Inc. Woodward is the oldest industrial manufacturer in America, founded in 1870, and still, today remains one of the leading industrial companies in the market. These 505 and 505E models are available from us here at AX Control Inc. as a part of our inventory of used, yet reconditioned and repaired digital hardware.
The 9907-164 unit is designed to control the steam turbine by operating a single extraction and/or the admission for the turbine. It utilizes the turbine’s split-stage actuators, either one or both of them, to drive the inlet valves for steam.https://www.weikunfadacai1.com/
This unit, like any of the 505 governor modules, is able to be configured in the field by the on-site operators. The menu-driven software is controlled and altered by the operator control panel integrated onto the front-facing side of the unit. The panel has a display of two lines of text, 24 characters per line.
The 9907-164 is outfitted with a series of discrete and analog inputs: 16 contact inputs (4 of them dedicated, 12 of them programmable), and then 6 programmable current inputs, at 4 to 20 mA. The standard features included into the 9907-164’s capabilities are the critical speed avoidance, valve limiters, the auto start sequence, and the first-out indicator for shutdowns.
FEATURES:
Microprocessor: The core component of the module is a microprocessor, which is a small, programmable chip capable of executing instructions and performing calculations. It serves as the control unit for the module.
Inputs: The controller module receives input signals from various sensors or external devices, such as temperature sensors, pressure sensors, switches, or other control modules. These inputs provide information about the system’s current state.
Outputs: Based on the input signals and programmed instructions, the controller module generates output signals that control actuators, motors, valves, displays, or other components in the system. It regulates and adjusts the system’s behavior according to the desired parameters.
Programming and Algorithms: The microprocessor in the controller module can be programmed using specific software or programming languages. The programming allows customization of the control logic, algorithms, and response characteristics of the system. Different control strategies, such as PID (Proportional-Integral-Derivative) control, can be implemented to achieve the desired performance.
Communication: Many controller modules support communication interfaces, such as serial communication (RS-232, RS-485), Ethernet, or fieldbus protocols (Profibus, Modbus). These interfaces enable the controller module to exchange data with other devices, such as human-machine interfaces (HMIs), supervisory control and data acquisition (SCADA) systems, or other controller modules in a distributed control system.
Real-Time Operation: Many controller modules operate in real time, meaning they can process input signals and generate output signals within specific time constraints. This capability is essential for applications where precise timing and responsiveness are crucial, such as robotics or motion control systems.
