Converteam Wago-I/O-IPC 758-873 Embedded industrial controller

The original WAGO standard model is 750-873 (ETHERNET TCP/IP + RS232 fieldbus controller); common spare parts suppliers often label it as 758-873, commonly known as WAGO-I/O-IPC. Converteam (formerly Alstom Transmission, later incorporated into GE Energy/Siemens) is its most well-known complete set of matching components, and is widely used in large power frequency conversion, ship propulsion, generator excitation, and wind turbine pitch control complete systems as a distributed I/O controller.

Basic Positioning

– Type: WAGO-I/O-SYSTEM 750 series **Programmable Fieldbus Controller (PFC), IEC61131-3 PLC**
