The WAGO 750-815/325-000 is a robust MODBUS RTU programmable logic controller (PLC) designed for decentralised industrial automation and control applications operating in demanding environments. As part of the proven WAGO-I/O-SYSTEM 750 series, this controller combines PLC functionality with MODBUS communication, enabling reliable machine control and distributed I/O management from a single compact device.
Developed for OEMs, panel builders and automation engineers, the controller supports IEC 61131-3 programming and allows direct access to both fieldbus and I/O data. By processing automation tasks locally, it helps reduce network traffic while improving overall system response times and reliability.
Featuring MODBUS RTU communication via RS-485, a 16-bit processor and an extended operating temperature range, the 750-815/325-000 is ideal for industrial machinery, process automation, building management and remote control applications where environmental conditions exceed standard controller specifications.
The WAGO 750-815/325-000 combines PLC functionality and MODBUS communication into a single compact controller. Its decentralised architecture allows local control of connected devices, reducing dependence on central PLC systems while improving machine responsiveness and reducing communication overhead.
The extended temperature specification makes this controller particularly suitable for industrial installations exposed to challenging environmental conditions, including outdoor enclosures, utilities infrastructure and remote automation systems.
