The Schneider Electric VW3A3307S371 is a Profibus DP V1 communication card that runs at 1.5 Mbps. It plugs into the Altivar drive option slot to put the drive on a Profibus DP fieldbus network — the V1 class supports acyclic data exchange alongside the cyclic process data, which matters for parameter uploads and diagnostics without interrupting the control loop.
What the standard means
California Proposition 65 listing means the product contains or exposes users to a chemical known to the State of California to cause cancer or reproductive harm. This is a labeling requirement, not a performance or safety standard — it does not affect the card's function or its suitability for the Profibus DP network. It is a compliance flag for shipments into or through California.
