The 505 and 505E are microprocessor-based controls designed to operate steam turbines of all sizes. The 505 is designed to operate steam turbines using one or two (split-stage) actuators to drive inlet steam valves. The 505E is designed to operate single extraction and/or admission steam turbines. These digital controls are field configurable. They use menu-driven software to instruct site engineers on programming the control to a specific generator or mechanical drive application. The 505 or 505E can be configured to operate as a stand-alone unit or in conjunction with a plant's Distributed Control System. Learn more from 505/505E product spec 85005.
505 Enhanced
The 505 Enhanced controller is designed to operate industrial steam turbines of all sizes and applications. It includes specifically designed algorithms and logic to start, stop, control, and protect industrial steam turbines or turbo-expanders, driving generators, compressors, pumps, or industrial fans. The control's unique PID structure makes it ideal for applications where it is required to control steam plant parameters like turbine speed, turbine load, turbine inlet or exhaust header pressure, or tie-line power. The control's special PID-to-PID logic allows stable control during normal turbine operation and bumpless control mode transfers during plant upsets, minimizing process over- or undershoot conditions. The 505 Enhanced controller senses turbine speed via passive or active speed probes and controls the steam turbine through one or two (split-range) actuators connected to the turbine inlet steam valves. For critical applications requiring increased reliability and redundancy, optionally two 505 controls can be connected in a redundant configuration to increase overall system availability.
