6ES5490-7SA21 is identified by Siemens as a Simulation Connector Assembly within the Simatic S5 family.
Simulation hardware supports testing and commissioning by providing a controlled way to exercise compatible control-system functions without relying solely on live process signals. Connection and configuration should follow the requirements of the platform.
In a SIMATIC S5 system, module selection is governed by the controller family, rack arrangement, electrical interface, and configured program. The exact article number should be matched before installation. Selection should account for the intended surrounding hardware configuration.
When this product is used for lifecycle support, technicians should confirm the installed revision, connection arrangement, and system assignment rather than assuming interchangeability with a similarly named module. System drawings should be consulted before replacement.
