iC7 Functional extensions

iC7 Functional extensions are modular option boards that add extra digital and analog inputs/outputs, relay contacts, temperature monitoring, voltage measurement, and encoder/resolver feedback interfaces to Danfoss iC7 drives. This lets integrators match drive I/O and feedback capability precisely to the application, from simple I/O expansion to advanced motion feedback and ATEX-compliant motor protection. Each option is purpose-built for a specific extension need, allowing flexible, scalable configuration of the drive platform.
