Schneider VW3A3407 Encoder Interface Card

Product Introduction

The Schneider Electric VW3A3407 Encoder Interface Card is a high-performance accessory for Altivar variable speed drives, designed to transmit encoder feedback signals directly to the drive for improved precision and operational performance. By capturing and sending encoder input data, the card enhances motor control accuracy, regardless of the motor’s operational state.

This interface card is equipped with RS422-compatible differential output, making it suitable for high-speed, reliable encoder communications. It is compatible with Altivar Lift, Altivar 61, Altivar 71Q, Altivar 71, and Altivar 61Q drive series, and is one of six selectable cards tailored to various encoder technologies. Fully RoHS-compliant, it meets European environmental and safety standards, ensuring industrial reliability and sustainability.
