The WAGO 750-881 is a 3rd-generation Ethernet programmable fieldbus controller built for the modular WAGO-I/O-SYSTEM 750, delivering reliable industrial automation control for digital and analog signal processing. The WAGO 750-881 features dual RJ45 Ethernet ports with an integrated 10/100 Mbit/s switch, supporting line topology wiring to eliminate extra network hardware in factory and process control setups. Programmed via CODESYS, this WAGO 750-881 controller offers ample program and data memory to handle multitasking control logic, remote monitoring, and Modbus communication for diverse industrial applications. It mounts easily on standard DIN-35 rails and uses WAGO’s proven CAGE CLAMP® spring connection technology, enabling fast, vibration-resistant wiring without ongoing maintenance. Compact in footprint, it helps designers save cabinet space compared with traditional standalone PLCs. Suitable for water treatment, manufacturing, building automation and other distributed I/O tasks, the WAGO 750-881 works seamlessly with hundreds of WAGO 750 series I/O modules to build flexible, scalable control nodes. Note that the WAGO 750-881 is an obsolete WAGO controller, ideal for replacement and spare part demands in existing automation systems where stable, tested hardware is required.
