Wago 750-862 Modbus TCP Controller, 24 V, 2-Port Ethernet

The Wago 750-862 is a 4th generation Modbus TCP controller engineered for robust industrial automation tasks. Operating on a 24 V power supply, this compact unit serves as a central programmable controller within Ethernet networks, seamlessly integrating with the WAGO I/O System. It automatically detects connected I/O modules to generate a local process image, supporting a flexible mix of analog and digital modules for comprehensive data processing.

Advantages

This controller features two integrated Ethernet ports with an internal switch, which facilitates line topology wiring and removes the requirement for external network switches or hubs. The device supports autonegotiation and Auto-MDI(X) for simplified network connectivity. With its multitasking capabilities and support for a wide range of standard Ethernet protocols, including HTTP(S), DHCP, and SNMP, it offers high versatility. The integrated web server allows for convenient configuration and real-time status monitoring, while the DIP switch enables easy IP address assignment.

Suitable for

• Industrial automation and control systems
• Modular I/O data acquisition
• Fieldbus communication in Modbus TCP networks
• Networked machine control in line topologies

This controller may not be suitable for applications requiring high-speed motion control or safety-critical functions that demand specialized safety-rated hardware. It is also not intended for outdoor environments without an additional protective enclosure, as it carries an IP20 rating.

Key specifications

• Supply voltage: 24 V
• Communication: 2 x Ethernet ports with integrated switch
• Protocols: Modbus TCP, HTTP(S), BootP, DHCP, DNS, SNTP, (S)FTP, SNMP
• Protection rating: IP20
• Dimensions: 49.5 mm x 71.9 mm x 96.8 mm
• Mounting: Wall-mounted

To use the Wago 750-862, mount the unit securely on a standard rail or wall surface. Connect the power supply to the designated terminals and link the Ethernet ports to your network infrastructure. Use the integrated web server or compatible programming software to configure the device and map your I/O modules. The DIP switch can be used to set the final byte of the IP address for network identification.

What to consider before purchase

• Ensure the 24 V power supply meets the system requirements
• Verify that the network topology supports line-based Ethernet connections
• Check compatibility with existing I/O modules in your system
• Confirm the environment is suitable for IP20-rated equipment

Ensure that all network cabling is properly shielded and that the controller is installed in a clean, dry environment to maintain optimal performance and longevity.
