The VW3A3101 is a 115 VAC logic input module from Schneider Electric, designed to accept 115 VAC signals into a control system. It is a straightforward interface for bringing line-voltage AC sensor or switch signals into a PLC or drive logic input bank, without needing an intermediate relay or signal converter.
The VW3A3101 is listed as compliant with California Proposition 65, which covers chemicals known to cause cancer or reproductive harm. This is a state-level labeling requirement, not a functional or safety standard for the module's operation.
