Integration Context
This IPD card mounts inside the SINAMICS S120 air-cooled Basic Line Module chassis. The module itself is a line-side infeed unit that provides a regulated DC-link voltage for multiple motor modules in a drive line-up. The card handles interface signals and protection functions between the control unit and the power section. When replacing this card, verify the firmware compatibility with the existing control unit and line module — the card is the communication and protection bridge, not a standalone drive component.
