Product details

Overview

The VW3A21312 is a Schneider LonWorks communication card for the Altivar 21 variable speed drive, using TP/FT-10 free topology at 78 kbps and connecting via a 3-way removable screw terminal block.

Schneider discontinued the VW3A21312 on 2023-10-02; no official successor is listed.

The closest functional peer is the VW3A3315, which also uses a single LED but for fault indication rather than service/reference display. Choose VW3A3315 when the BOM requires a fault LED; otherwise the VW3A21312 remains the correct LonWorks card for Altivar 21 drives.
