We currently stock a fare number of brand new OEM Flex 3000 Amx Network Kits. They are used inside the FlexPak 3000 drives to communicate over an AutoMax Network. If you are trying to get your FlexPak 3000 to communicate to a newer PLC, say a ControlLogix, then we recommend using a bridge to go between the Ethernet/IP network and the Automax Network. This communication card and a QTSI module is a great solution to that problem. Only one QTSI module would be required to talk to one or more drives.
