Product Description
ALSTOM SPU232.2, Part No.029.366.817, CAN System Single Processor Board. It acts as core CPU unit for Alspa 6000 control system. OEM production is obsolete, classified as GE Vernova legacy spare part. This board integrates single‑processor core and galvanic‑isolated CAN 2.0B bus interface. It executes system logic operation, signal processing and synchronisation calculation, communicates with rack I/O modules via CAN bus to realise generator synchronisation logic, data acquisition and alarm output.
