The VW3A3E319 is a BACnet communication card for Altivar variable-speed drives, letting the drive talk BACnet MS/TP on a building-automation network. It connects via a 9-way female SUB-D connector — the standard RS-485 pinout for BACnet MS/TP daisy chains. Two LEDs on the faceplate show network traffic (COM) and fault (ERR) status; the card also passes control-word and reference-word received signals to the drive's graphic display terminal.

Frequently asked questions
Where can I buy VW3A3E319?
We source and quote the VW3A3E319 to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock figures or lead-time numbers on this page.
What is the closest pin-compatible alternative to VW3A3E319?
There is no pin-compatible direct replacement from Schneider Electric. The BACnet option cards for current Altivar generations (Altivar Process, Altivar Machine) use a different form factor and connector. For a legacy Altivar drive that needs BACnet, the VW3A3E319 is the only card that fits the option slot.
What does the display and LED status on VW3A3E319 show?
The card has one LED for COM (network traffic) and one LED for ERR (fault). It also provides graphic display terminal signals for control word received and reference word received — these appear on the drive's own display when the card is installed.
