## Summary description

The Wago 750-891 is a programmable logic controller designed for industrial automation and network control. It operates on a supply voltage range of 18-31.2 V DC and features an IP20 protection rating. This wall-mounted controller is engineered for reliable performance in modular control systems, providing efficient data processing and communication capabilities for various industrial applications.

## Long description

The Wago 750-891 is a high-performance programmable logic controller engineered for industrial automation and efficient network control. Designed to operate within the WAGO I/O System, this controller facilitates seamless data processing by detecting connected I/O modules and creating a local process image that supports both analog and digital data transfer. With its dual ETHERNET interfaces and integrated switch, it enables flexible line topology wiring, reducing the need for external networking hardware.
Advantages
This controller offers significant flexibility through its support for a wide range of standard ETHERNET protocols, including HTTP(S), DHCP, and SNMP, ensuring compatibility with diverse industrial environments. The inclusion of an integrated web server allows for convenient configuration and real-time status monitoring. Furthermore, its multitasking-capable architecture and capacitor-backed real-time clock ensure reliable performance and data integrity during operation. The device is built for robust fieldbus communication, specifically optimized for Modbus networks.
Suitable for
Industrial automation and control systems
Modbus TCP network communication
Modular I/O signal processing
Ethernet-based fieldbus applications
When it may not be suitable
This controller is rated with an IP20 protection level, meaning it is not suitable for environments exposed to dust, moisture, or liquids without additional protective housing. It is intended for installation within a control cabinet or protected enclosure.
Key specifications
Supply voltage: 18-31.2 V DC
Protection rating: IP20
Mounting type: Wall-mounted
Dimensions: 61.5 mm width, 71.9 mm depth, 100 mm height
Communication: Dual ETHERNET interfaces with integrated switch
Programming standard: IEC 61131-3
How to use
The controller is designed for wall mounting within a standard industrial control cabinet. Once mounted, connect the necessary I/O modules to the system, which the controller will automatically detect. Use the integrated ETHERNET ports to establish network connections in a line topology. Configuration can be managed via the built-in web server or by using the DIP switches to assign the IP address. Ensure the power supply is within the specified 18-31.2 V DC range before activation.
What to consider before purchase
Verify that your network infrastructure supports Modbus TCP protocols.
Ensure the installation environment meets the IP20 protection requirements.
Check that your existing I/O modules are compatible with the WAGO I/O System.
Confirm that the power supply unit provides a stable voltage within the 18-31.2 V DC range.
Usage recommendations
Always ensure the controller is installed in a well-ventilated enclosure to maintain optimal operating temperatures and prevent dust accumulation, as the IP20 rating does not provide protection against environmental contaminants.
