Features:
- Legacy AC31 controller: Designed for ABB Series 90 automation systems.
- Integrated system role: Central processing and onboard resources support installed AC31 applications.
- Migration context: ABB identifies AC500 as the successor platform for AC31.
07KT94 serves as the central unit in an installed AC31 Series 90 controller architecture.
Because wiring, software, and interface use can vary by installation, replacement decisions must start from the actual nameplate and project records.
A controlled modernization plan should preserve the original program and I/O behavior while validating any required AC500 migration changes.
Availability is subject to Apter Power's current inventory and sourcing confirmation.
