Schneider Electric VW3A21315 BACnet Communication Card

Schneider Electric VW3A21315 BACnet Communication Card is the BACnet option module for Altivar 21 drives, enabling direct integration of HVAC equipment with BACnet building automation networks. The card installs in the ATV21 drive’s communication block and provides BACnet connectivity (along with Metasys N2 and APOGEE capabilities) via an open RJ45 style connector for straightforward network wiring. Typical data-rate support spans 9.6 kbps to 76.8 kbps, supporting reliable BACnet communications in commercial HVAC installations, with a dedicated COM LED on the card to indicate network traffic for quick diagnostics. Designed for Altivar 21 HVAC applications, this card enables centralized control, monitoring, and data exchange between Schneider Electric drives and BACnet-enabled BAS controllers, energy management systems, and other building devices, reducing integration complexity and improving control of motor-driven HVAC components such as fans and pumps.
