ABB SDCS-CON Series Technical Notes

The Evolution of SDCS-CON Architecture

The SDCS-CON lineage traces to ABB's transition from the analog-controlled DCREG and MENTOR platforms toward fully digital DC drive control in the early 1990s. The original SDCS-CON-1 introduced microprocessor-based speed regulation with serial parameter access, replacing potentiometer-based tuning. The SDCS-CON-2 (part number 3ADT220090R0001) extended this with expanded I/O capacity and support for the SDCS-FEX field excitation modules, becoming the dominant variant in DCS400 installations through the late 1990s and 2000s.
