DEIF AWC 500 Series Advanced Controller Product Introduction

The AWC 500 is a highly‑flexible modular process controller developed by DEIF. Designed for harsh operating conditions, it delivers high reliability, robust performance and flexible configuration. It is primarily deployed in the wind‑power industry for wind turbine main control, pitch control, grid protection and distributed I/O control, and can also be applied to other industrial scenarios requiring complex process control. The complete system is built by combining racks with various functional modules communicating over the EtherCAT bus. It supports two development approaches: C/C++ and IEC 61131‑3 (CODESYS).
