CANopen Fieldbus Option for ATV312 Drives
The Schneider Electric VW3A31208 is a CANopen fieldbus option card designed for the ATV312 series of variable speed drives. It slots into the drive's communication bay, giving the drive a CANopen interface for control and monitoring over a fieldbus network. This card handles the CANopen protocol, so the drive can take speed references, start/stop commands, and report back status and diagnostics over the bus. It is the standard way to integrate an ATV312 into a CANopen-based automation cell.
This option card is listed as compliant with California Proposition 65, the state's Safe Drinking Water and Toxic Enforcement Act. That means the manufacturer has certified the product does not expose users to listed chemicals above the safe-harbor level, or has provided the required warning. No other standards (RoHS, REACH, UL, IEC) are recorded in the listing for this code.
