£653.31
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.
The WAGO 750-889 is specifically designed for intelligent building automation systems where KNX integration is essential. The controller can operate as a programmable KNX IP controller or, when combined with a KNX/EIB/TP1 module, function as a KNX IP router on an Ethernet backbone. This flexibility makes it suitable for both new installations and system expansions.
Its integrated Ethernet switch simplifies network architecture, while support for protocols such as HTTP, DHCP, DNS, FTP, SNMP and SMTP enables advanced diagnostics, monitoring and remote management capabilities. The controller is fully programmable using IEC 61131-3 languages and WAGO-I/O-PRO software.
