GE 531X309SPCAJG1 Digital Signal Processor Card

Product Overview

The GE 531X309SPCAJG1 is a digital signal processor (DSP) card engineered for General Electric DC2000 Digital Adjustable Speed Drive systems. As part of the GE 531X printed circuit board family, this module performs high-speed signal computation, logic execution, and field interface coordination within GE drive control architectures.

Designed for continuous industrial operation, the card functions as a core signal processing and control interface when installed alongside the SDCC Drive Control Card. Its DSP-based design ensures precise timing, reliable communication, and stable output control in demanding drive and turbine-related environments.

Frequently Asked Questions

Q: Is this card interchangeable with other 531X signal processor boards?
A: No. Although physically similar, functionality and firmware vary by revision. Always match the exact model number 531X309SPCAJG1.

Q: Does this module function as a standalone output card?
A: It operates as a signal processing and control interface and works in conjunction with the SDCC Drive Control Card rather than as an independent output module.

Q: Is this suitable for Mark VI systems?
A: This board is primarily associated with DC2000 and related GE drive platforms. Mark system compatibility should be verified against GE engineering references.
