£826.27
The WAGO 750-890/040-000 is a high-performance 4th generation Modbus TCP programmable controller engineered for industrial automation systems operating in extreme environmental conditions. As part of the robust WAGO I/O System 750 XTR series, this controller combines advanced PLC functionality, Ethernet networking and modular I/O integration within a compact DIN rail-mounted platform.
Designed specifically for harsh industrial environments, the controller supports Modbus TCP and Modbus UDP communications while offering increased immunity to electromagnetic interference, higher vibration resistance and enhanced surge protection. Its dual Ethernet interfaces and integrated switch simplify network architecture and reduce installation costs.
Featuring a powerful 32-bit processor, 8 MB program memory, 8 MB data memory and an integrated SD card slot, the 750-890/040-000 delivers reliable performance for demanding control applications. The XTR version supports an extended operating temperature range from -40°C to +70°C, making it ideal for outdoor installations, utilities and critical infrastructure projects.
The WAGO 750-890/040-000 is specifically engineered for applications where environmental conditions exceed the capabilities of standard automation controllers. The XTR design provides greater resistance to vibration, shock, electromagnetic interference and voltage surges, ensuring reliable operation in demanding industrial environments.
The integrated Ethernet switch enables efficient line topology configurations without requiring additional network hardware. Combined with support for IEC 61131-3 programming languages and advanced diagnostics through the integrated web server, the controller delivers a flexible and scalable automation platform for critical applications.
