Product Overview

• Part No: 730475-D, ELEMENTS-F2
• Brand: ALSTOM

• Category: Turbine Main Processor Control Module730475-D ELEMENTS-F2 is a Eurocard plug-in 32-bit microprocessor main controller for ALSTOM legacy steam turbine governing systems. It serves as the central processing unit for single extraction, extraction/intake and condensing steam turbines. The module executes turbine speed closed-loop regulation, extraction pressure control, load setpoint management, protection interlock logic and fault monitoring. It supports on-site field programming to adapt to multiple turbine configurations, and communicates with I/O modules, HMI and upper monitoring systems via internal rack bus. Equipped with built-in self-diagnosis, surge filtering and EMC protection circuits, it ensures stable continuous operation under severe electromagnetic interference inside power plant control cubicles. It is a discontinued original critical spare used for maintenance and retrofit of thermal power plant turbine control equipment.
