Product Overview

• Part No: N895313512X
• Brand: ALSTOM

• Category: Multifunctional SUP-AL Control ModuleN895313512X is a standard Eurocard draw-out control module belonging to ALSTOM legacy turbine control product family. It integrates analogue signal conditioning, digital logic processing and backplane bus communication interfaces. The module acquires field sensor signals including pressure, temperature, displacement and vibration, converts raw analogue measurements into digital data and exchanges real-time process information with system master controllers. Equipped with built-in filtering, galvanic isolation and surge suppression circuits, it maintains stable operation under severe electromagnetic interference inside power plant control cubicles. It serves as critical replacement spare for steam turbine governing cabinets and distributed control systems of thermal power stations and combined-cycle power plants.
