The Schneider Electric VW3A7281 is a communication bridge card that extends fieldbus connectivity for Altivar speed drives when paired with an Altivar AFE and a fieldbus option card. It sits in the drive's option slot, translating between the drive's internal bus and additional fieldbus protocols.
This part is obsolete.
The card measures 150 mm wide, 200 mm tall, and 25 mm deep — a compact profile that fits inside the Altivar drive enclosure without adding external DIN-rail space. Verify the host drive's option slot compatibility and the specific fieldbus option card required for your network (Profibus DP, DeviceNet, Ethernet/IP, etc.) before ordering.
