  FedEx, UPS, or DHL – you can choose at checkout.

• Is mounting hardware included?

  Yes, insulation bushings and M5 screws are provided.

Selection Guide

• For high availability → choose dual‑redundant power and Vnet/IP.
• For smaller systems → consider AFV10S (single CPU).
• Check your power supply voltage before ordering (AC or DC).
• Ensure node count ≤14 and ESB nodes ≤9.
