Don’t let a discontinued part paralyze your production. Your legacy ABB system still has years of life left.
At Moore Automation, we act as the "specialized first-aid warehouse" for the world's industrial giants. When your plant faces a shutdown because an ABB AC31 (Series 40, 50, or 90) module has failed and the original manufacturer says "obsolete," we step in. We specialize in sourcing the hard-to-find, the discontinued, and the mission-critical "brains" of your operation.
With a massive on-site inventory, we offer faster delivery than the OEM and provide an exclusive one-year warranty on all parts, ensuring your twenty-year-old equipment stays as reliable as the day it was installed.
We carry a comprehensive stock of genuine ABB spares to keep your CS31 system bus operational:
Is it time to modernize without the headache of a total system overhaul? We provide the AC31 Adapter series, allowing you to bridge the gap between legacy hardware and current AC500 technology

Reliable hardware does more than restore function—it guarantees industrial resilience. From the critical processing power of the 07KT98 CPU to the seamless integration of AC31 Adapters, Moore Automation delivers the essential infrastructure required for sustained productivity. Eliminate the risk of obsolescence and maintain a facility built for uninterrupted performance.
A: Yes, but note that because the adapter is based on AC500 hardware, you must rewrite the application program using Automation Builder. A direct software import from the old AC31 system is not possible.
A: Perfectly. Care was taken during development to ensure the footprint and cabling positions remain identical to the original AC31 Series 90.
A: No. AC31 adapter I/O modules are specifically designed to work with ABB CPUs featuring a master CS31 bus.
A: That is our specialty. We maintain a "first-aid" stock of surplus and new-old-stock items to ensure you have a replacement even when ABB has stopped production.
