505E

Extract./Admis., LV/AC

The 2nd generation 505E product line is available as spare units for existing systems. It is no longer available for installation on new systems. For replacement products, see the 505D, 505XT and Flex500. This 505E controller is designed to operate single-extraction and/or admission steam turbines in a single or redundant configuration. This steam turbine controller includes specifically designed algorithms and logic to start, stop, control, and protect single extraction and/or admission steam turbines or turboexpanders, driving generators, compressors, pumps, or industrial fans. The 505E 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 pressure, exhaust header pressure, extraction or admission header pressure, or tieline power."
