At-A-Glance Executive Brief
- Model: IC697CPX928, Alstom drawing reference M0009483
- Brand: GE Fanuc
- Part Type: Series 90-70 single-slot PLC CPU module
- Lifecycle status: OEM obsolescent, stocked for brownfield power and process sites
- System compatibility: Fits IC697 chassis, works with Genius I/O networks
- Weight: 0.5kg
Technical Introduction
Field sites running Alstom turbine and boiler controls rely on this CPU as the core logic executor for large legacy Series 90-70 racks. This 96 MHz 80486DX4 processor runs 32-bit floating-point math and Boolean logic at 0.4µs per instruction. It uses 6MB battery-backed RAM paired with 256KB flash storage, and three built-in serial ports handle local programming and Genius I/O communications. It occupies one primary rack slot and coordinates all backplane I/O mapping across up to 12,000 digital points. Many power generation facilities keep this part on hand to delay full legacy system migration.
- Best Suited For
- Alstom branded power plant Series 90-70 control racks
- Large mixed analog/digital process control systems
- Sites needing direct drop-in CPU replacement without rack rework

Field Engineer’s Tech Notes
- The internal lithium battery holds RAM data for roughly six months. If the module sits in storage for longer, expect program loss after installation. Always back up the user logic before removing the old CPU.
- Forced airflow must meet 70 CFM to maintain full temperature rating. Reduced rack cooling can trigger intermittent CPU resets under heavy floating-point calculation loads.
Adaptive QA & Testing Protocol
Each unit gets backplane insertion testing on a Series 90-70 test chassis. We verify front-panel LED status, execute memory read/write checks across RAM and flash, and validate RS232 and RS485 port handshake with SNP and Genius I/O simulation. Floating-point instruction cycles run through a test logic program to confirm processor integrity. Full test reports or short video capture of the bench cycle are available upon request.
Buyer’s FAQ
Q: Does M0009483 equal IC697CPX928? A: Yes. M0009483 is the Alstom drawing reference number; the hardware OEM part number remains IC697CPX928, fully drop-in compatible.
Q: What warranty comes with refurbished or NSFP units? A: Refurbished units carry a 12-month warranty. New surplus NSFP parts ship with a 12-month warranty covering hardware defects, excluding onsite labor and battery wear.
Q: What lead time should I expect for shipment? A: Stocked units ship in 3–7 business days. If inventory is depleted, lead time extends while we source available used or NSFP stock.
Q: Can I swap this CPU without reloading my existing PLC program? A: Only if the backup battery retains memory after removal. Standard practice is to export and archive logic to avoid data loss during the swap.
