£435.36
The WAGO 750-842 is a powerful Ethernet programmable fieldbus controller (PLC) designed for industrial automation, machine control and distributed I/O applications. As part of the proven WAGO I/O System 750 series, this controller combines PLC functionality, Ethernet networking and modular I/O control within a compact DIN rail-mounted device.
Developed for demanding industrial environments, the 750-842 enables decentralised control architectures that improve system performance, reduce network traffic and simplify machine automation. The controller supports IEC 61131-3 programming and provides flexible communication through Ethernet TCP/IP and MODBUS/TCP protocols.
With integrated processing capability, support for up to 64 I/O modules and reliable Ethernet communications, the WAGO 750-842 is an excellent choice for machine builders, system integrators and industrial automation engineers seeking scalable and efficient control solutions.
The WAGO 750-842 combines control functionality, networking and I/O management into a single industrial automation platform. By processing signals locally, the controller reduces communication overhead while improving machine responsiveness and overall system efficiency.
Support for IEC 61131-3 programming allows engineers to develop sophisticated control strategies using standard industrial programming languages. The controller can operate as a stand-alone automation solution or as part of larger distributed control systems.
