Overview
The VW3A3E307 is a Profibus DP communication card for the Schneider Altivar 61 Plus and Altivar 71 Plus drive ranges, transmitting at up to 12 Mbps over a 9-way female SUB-D connector. It supports up to 126 addresses on the Profibus network and provides two LEDs for data exchange and status indication.
Lifecycle and sourcing
Schneider discontinued the VW3A3E307 on 2024-04-09; no official successor is listed, so remaining units are sourced through surplus and broker channels. For a line-down or last-time-buy situation, an RFQ confirms available quantity and lead time from the surplus market.
How it compares
The VW3A3E307 uses Profibus DP with a 9-way SUB-D connector, while the VW3A3E310D uses Modbus TCP over an RJ45 connector — choose the VW3A3E307 for existing Profibus DP networks and the VW3A3E310D for Ethernet-based control.
