performs the core control and protection functions of a small steam turbine package. The application software is field configurable, allowing it to be configured and modified to meet site-specific requirements. Modbus communications also allow easy interface with a package PLC or plant DCS.

The 2301E-ST has four operating modes:

  • Speed Control

  • Has multiple dynamics flexibility. Will work on pumps or compressors. Has capability for remote 4–20 mA speed reference through  configurable analog input.

  • Isochronous Load Sharing

  • Is compatible with most existing analog load sharing speed control systems. Now with soft load and unload capability.

  • Droop Base Load

  • Adjustable load control using discrete raise and lower contact

  • Isochronous Base Load

  • Provides constant load level operation against a utility bus. The load setting may be fixed orchanged using discrete raise and lower inputs or a remote 4–20 mA input.
