6SE7090-0XX84-0KA0 New

The Siemens 6SE7090-0XX84-0KA0 is an ADB (Adapter Board) for the SIMOVERT MASTERDRIVES Motion Control platform, designed for use with compact and chassis-type drive units. This module serves as the mechanical and electrical interface that enables specific option boards to be installed in the drive's internal electronics slot . In the modular architecture of MASTERDRIVES MC (Motion Control) systems, the ADB provides the physical carrier platform and electrical connectors needed to fit miniature-format option boards into the electronics box. The ADB itself is not a functional control module — it is a mandatory carrier platform that, when combined with a Local Bus Adapter (LBA), allows the installation of expansion boards that would otherwise be mechanically or electrically incompatible with the drive unit.
