WAGO 750-842 Ethernet Controller

The WAGO 750-842 Ethernet Controller is an industrial automation device that executes PLC logic and enables reliable Ethernet communication between WAGO I/O modules, HMIs, and networked industrial devices. Part of the WAGO-I/O-SYSTEM 750 family, this 24 V DC-powered controller supports 10/100 Mbit/s Ethernet, TCP/IP and Industrial Ethernet protocols, and includes integrated PLC functionality with programming in CoDeSys (IEC 61131-3). It mounts on a DIN rail and uses an industrial thermoplastic housing with integrated LED diagnostics for quick status checks. Compatible with WAGO 750 Series I/O Modules, it serves distributed automation and machine control across packaging machinery, conveyor systems, material handling equipment, OEM automation equipment, and process control skids where dependable PLC capability and Ethernet connectivity are needed. Web-based configuration and diagnostics facilitate setup and monitoring, while the controller supports common factory automation tasks such as process monitoring, machine control, and remote device communication. Common replacements include 750-841, 750-881, and 750-880.
