6SE7090-0XX84-0AH2 NEW ORIGINAL 6SE7090-0XX84-0AH2

The Siemens 6SE7090-0XX84-0AH2 is a T300 Technology Board for the SIMOVERT MASTERDRIVES drive platform. It is a plug-in option board that adds supplementary process-specific functions—such as tension control, winder control, angular synchronism, positioning, and hoisting gear functions—to the drive's core control capabilities. This board is the direct successor to the 6SE7090-0XX84-0AH0 (T300). According to Siemens Industry Support, the AH2 is a hardware revision of the same T300 platform, with no programming differences between the two versions. The only practical migration note is that the MS300 module must be transplanted from the old board to the new one.
