EtherCAT Fieldbus system
What is EtherCAT?
EtherCAT (Ethernet for Control Automation Technology) is an open, Ethernet-based fieldbus standard originally developed by Beckhoff Automation, which is being further developed in the EtherCAT Technology Group (ETG). EtherCAT enables communication between devices from different manufacturers without special interface adaptations and is used mainly in automation technology.
EtherCAT ASi
EtherCAT ASi-3 Gateways in stainless steel provide an interface for an EtherCAT fieldbus. These ASi gateways are available in various versions with IP20 protection rating.

| Figure | Type | Model | "IP20": "IP40": Protected against solid foreign bodies having a diameter of 1.0 mm or larger, protected against access with a wire, no protection against water. "IP54": Protection against dust in damaging amounts, complete protection against contact, protection against splashing water in any angle.
Dust-tight, full protection against contact, protection against temporary immersion. |
