Product Description
The WOODWARD 2301E-ST 8273-1014 is a digital electronic load-sharing and speed-control system designed for small single-valve steam turbines. It integrates turbine speed regulation, load control, valve limiting, shutdown logic, alarm management, and diagnostic functions into one industrial controller.
The 8273-1014 is the hazardous-location version of the 2301E-ST, designed for applications requiring suitable hazardous-area installation approval. It operates with a 24 VDC nominal power supply and supports configurable control strategies for steam turbine generator sets, pumps, and compressor drives.
The controller can be configured and monitored using a PC through its serial communication interface and Woodward service software. Its field-configurable application software allows engineers to adapt control parameters to individual turbine operating requirements.
