The Peak 150 digital control is designed to control a steam turbine driving a mechanical load. It provides tight control of speed (NEMA D) and includes an input for a 4–20 mA remote speed control signal, which can be used for a processgenerated input to control the speed setting. Other features include dual speed control dynamics and overspeed trip test capabilities. (product spec 85549)
The ProTech 203 Overspeed Protection System monitors three individual magnetic pickups (MPUs) to provide overspeed protection for steam and gas turbines and other prime movers. The system replaces mechanical overspeed devices, especially in high-speed applications (above 10,000 rpm) when a mechanical overspeed device becomes unreliable. (product spec 85562)
The 5009 control is designed to provide highly reliable control on critical steam turbine applications. It can be configured to control condensing, backpressure, and single automatic extraction/admission turbines. The 5009 is field programmable and uses Windows™ menu-driven software to guide site engineers on configuring the control to a specific generator or mechanical drive application. The 5009 can be configured to operate as a stand-alone unit or in conjunction with a plant's Distributed Control System. (product spec 85578)
The 505DE is a microprocessor-based control with integral application software that is designed to control double automatic extraction/admission steam turbines. The turbine control architecture is patterned after the popular 505E Single Extraction/Admission Steam Turbine Control. Like the 505E, the 505DE uses configurable software for maximum field flexibility. The control hardware consists of four plug-together modules housed in a rugged metal chassis. The SmartCore module and the Analog I/O module contain the I/O required for double extraction turbine control. The main processor and the Ethernet port are located on the Pentium CPU module. The Power Supply module (24 Vdc) is provided to power the entire control assembly. The control also contains 12 relay drivers for external use. (product spec 03312)
