WOODWARD_9907-164 unit Input/output module

ABOUT THE 9907-164

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.

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.

Key Features

High-precision control: using advanced digital microprocessor technology to achieve precise control of turbine speed, load and other parameters.

Abundant control functions: including speed control, load control, start and stop control of compressor and turbine, etc., meeting the control requirements under various complex working conditions.

Data acquisition and monitoring: capable of acquiring and monitoring data related to the performance of the turbine, such as rotational speed, temperature, pressure, etc., to ensure that the turbine operates in a safe and effective working interval.

Communication interface: supports various communication interfaces, such as serial communication (RS-232, RS-485), Ethernet or fieldbus protocol (Profibus, Modbus), which facilitates data exchange and remote monitoring with other devices.

Self-diagnostics and fault detection: With self-diagnostic function, it is able to detect turbine faults and provide alarms to improve the reliability and safety of the system.

Highly flexible: as with any 505 governor module, the unit can be configured in the field by the field operator, with menu-driven software controlled and changed from the operator control panel integrated on the front of the unit.

Technical specifications

Input Interface: Includes 16 contact inputs (4 dedicated and 12 programmable) and 6 programmable current inputs ranging from 4 to 20 mA.

Display and Control: The operator control panel on the front of the unit displays two lines of text, 24 characters per line, for controlling and changing the menu-driven software.

Standard Features: Includes critical speed avoidance, valve limiters, automatic start sequence and shutdown first-out indicator to ensure that an emergency shutdown can be prepared when starting an engine, turbine or other type of prime mover, preventing personal injury from loss of control or overspeed.
