The Schneider VW3A3501 is a high-performance Controller Inside programmable card designed for Altivar 61 and Altivar 71 variable speed drives, enabling embedded control logic directly inside the drive. Instead of relying on an external PLC, this module allows users to implement advanced automation, sequencing, and process control functions within the drive itself, significantly simplifying system architecture and improving response speed.
This solution is widely used in complex machine systems, process automation, and OEM equipment where integrated control and reduced cabinet complexity are required.
