Description and purpose
|
IC693CPU331-AA is the complete revision identity of the single-slot CPU331 used in GE Fanuc Series 90-30 systems. Official CPU331 hardware data identifies a 10 MHz 80188 processor, 16 KB maximum user memory and an SNP serial programming connection through the power-supply connector. It belongs in slot 1 of a compatible CPU baseplate. A CPU replacement affects more than the processor module. Confirm the baseplate, system PROM and firmware, battery condition, protocol support, communication setup and the saved Logicmaster or PAC Machine Edition project. The -AA code must remain in the RFQ and maintenance record; interchangeability with another revision requires an engineering check. |
Purchase verificationSend the complete IC693CPU331-AA label, baseplate and power-supply models, system PROM or firmware information, battery status, expansion layout and a verified project backup. We will compare the exact legacy configuration before quotation. |

Product image and identification notes
What buyers should verify in the photos
Use clear front, side and connector views to confirm the complete IC693CPU331-AA identity, suffix, revision, terminal or port arrangement, housing condition and installed accessories.
For an installed-system replacement, compare the photographed unit with the project hardware catalog and the component being removed. Appearance alone does not prove interchangeability.
FAQ about IC693CPU331-AA
Can I install any CPU331 revision in place of IC693CPU331-AA?
Not without an engineering check. Compare the complete revision code, system PROM and firmware, baseplate, project software, memory use, communication protocol and expansion hardware before substitution.
What must be backed up before removing IC693CPU331-AA?
Save logic, hardware configuration, register or retained-data requirements and communication settings. Record the current RUN/STOP state and battery condition before power is removed.
Where does IC693CPU331-AA install?
Official Series 90-30 hardware guidance places the single-slot CPU331 in slot 1 of a compatible CPU baseplate. Do not treat an expansion baseplate as a CPU baseplate.
What should I check if the replacement powers up but will not run the project?
Compare the system PROM and firmware, memory capacity, project target, I/O configuration and any password or protection state. Review the CPU and I/O fault tables before changing hardware again.
How should I protect the stored program during maintenance?
Maintain a verified offline backup and observe the battery-replacement procedure. Do not depend on RAM retention alone when the battery age or service history is unknown.
What information should I provide for an IC693CPU331-AA quote?
Send the full CPU label, system PROM or firmware, baseplate and power-supply labels, installed module list, project software version, quantity and destination.
