ASi EtherCAT Gateways - high availability and ideal for Beckhoff PLC
EtherCAT Gateways with and without integrated safety monitor available in large quantities
You are looking for ASi gateways – with or without FSoE interface – to connect AS-Interface (ASi) to an EtherCAT control? And you want to implement functional safety without a higher-level safe control? Then you will find suitable devices from us.
For standard applications:
ASi EtherCAT Gateways without integrated safety monitor
We recommend the "Bihl+Wiedemann's Choice" articles BWU3854, BWU4790 and BWU2720 for almost all standard applications. Here you also benefit from our new power supply generation.

For Safety applications:
ASi-3 EtherCAT Gateways with integrated safety monitor
For applications with functional safety without higher-level safe control, we recommend our ASi EtherCAT gateways with integrated safety monitor. They are available with 1 ASi network or 2 ASi networks.
For Safety over EtherCAT applications:
ASi-5/ASi-3 Safety over EtherCAT Gateways
For applications in which Safety over EtherCAT (FSoE) devices are to be integrated without a higher-level safety controller, we recommend our ASi-5 Safety over EtherCAT Gateways. With the integrated FSoE master function, for example, up to 32 FSoE drives can be safely switched off directly.
