ALSTOM SPU232.2 029.366 817 CAN System Single Processor Board

Product Description

ALSTOM SPU232.2 (part number 029.366.817) is a Signal Processing Unit processor card for ALSTOM ALSPA series DCS systems, manufactured in Germany. It is OEM discontinued and circulated as spare part for legacy power‑plant control systems. As a rack‑mount board, it serves as local processing core of the system, performing digital & analog signal pre‑processing, logic operation, timer/counter functions and interlock protection. It exchanges data with other I/O and communication modules via back‑plane bus to implement sequence control and protection logic for power‑plant equipment. On‑board hardware diagnostics and LED status indicators are provided, and redundancy configuration is supported for non‑stop power‑plant operation. Complying with IEC EMC standards, it works reliably under cabinet‑side harsh conditions of heavy electromagnetic interference and temperature variation. It is widely used for component replacement and overhaul of thermal, hydro and combined‑cycle power‑plants. No direct drop‑in replacement is available.
