The VW3A3309 is a DeviceNet fieldbus option card designed for the Schneider Electric ATV71 series of variable speed drives. It plugs into the drive's option slot to provide DeviceNet connectivity, allowing the ATV71 to communicate on a DeviceNet network for control and monitoring.
The card carries a California Proposition 65 listing, which is a state-level warning requirement for products containing substances known to cause cancer or reproductive harm. This listing does not affect functionality or safety in normal industrial use; it is a labeling compliance note for the US market.
With a mature lifecycle stage, the VW3A3309 is still available through distribution channels but should be considered for critical-spare stocking if you have ATV71 drives on DeviceNet.
