ALSTOM SPU232 029.354.630 REV 02 Signal Processing Unit Board

Product Description

The SPU232 (029.354.630, Revision 01) is a VME-bus signal processing board for Alstom / Converteam turbine and generator control systems, working in pair with ICP232 intelligent control processor. It is responsible for high-speed acquisition, conditioning and pre-processing of analog and pulse signals from field sensors, including speed probes, vibration transducers, current and voltage signals. It transfers filtered, synchronized data to the ICP232 main processor via VME backplane for closed-loop control and protection calculation. REV 01 is an early stable hardware revision of this signal interface card.

FAQ

Q: What is the relationship between SPU232 and ICP232?
A: ICP232 is the main intelligent control processor; SPU232 is the auxiliary signal pre-processing board, they must cooperate in one control rack.

Q: What does REV 01 mean?
A: REV 01 is the original hardware revision of 029.354.630, later revisions fixed minor component layout issues.

Q: Is this part still in production?
A: No, this legacy Alstom control board is end-of-life, only available as surplus, refurbished and tested spare parts.

Q: Can SPU232 work alone without ICP232?
A: No, it cannot run independently; it depends on ICP232 for logic operation and communication.
