ABB 1SAP14050099952 - EC583 CPU Module (AC500-eCo)

The ABB 1SAP14050099952 is the order code for the EC583 CPU module used in ABB AC500-eCo compact PLC systems, identified consistently by multiple specialists, including listings that also show the EC583-ETHi designation. The module executes user logic and manages local I/O on the eCo platform, where it slots into the compact eCo CPU carrier. Distributor listings disagree on the program memory figure (one states 16KB, another 64kB), so memory and firmware details should be confirmed against your installed unit before ordering. Used and refurbished units are offered with multi-month warranty from several independent dealers.
