Why Choose the WAGO 750-889 KNX IP Controller?

The WAGO 750-889 is a powerful KNX IP programmable controller designed for intelligent building automation, industrial control and distributed I/O applications. As part of the highly regarded WAGO I/O System 750 series, this controller combines PLC functionality, KNX IP networking and modular I/O expansion within a compact DIN rail-mounted platform.

Designed for advanced automation projects, the controller supports both KNXnet/IP and Modbus TCP/UDP communications while providing seamless integration with KNX building management systems. Combined with WAGO I/O modules, the controller delivers flexible automation capabilities for lighting control, HVAC systems, energy management and smart building applications.

Featuring a powerful 32-bit processor, 1024 KB program memory, 1024 KB data memory and an integrated dual-port Ethernet switch, the 750-889 offers reliable performance for demanding automation environments while supporting up to 250 I/O modules per node.
