WAGO 750-333 PROFIBUS DP/V1 fieldbus coupler for connecting WAGO I/O System 750/753 modules to PROFIBUS industrial automation networks.
£328.14
The WAGO 750-333 is a PROFIBUS DP/V1 fieldbus coupler designed to connect the modular WAGO I/O System 750/753 to PROFIBUS automation networks. Acting as the communication interface between field devices and PLC controllers, the coupler exchanges process data between connected I/O modules and the PROFIBUS master system.
During system start-up, the coupler automatically detects the installed I/O modules and creates a process image of all inputs and outputs. Digital signals are transmitted bit-by-bit, while analogue signals are transferred as bytes or words, allowing efficient communication between sensors, actuators and the automation controller. :contentReference
Supporting up to 63 I/O modules and approximately 6000 I/O points per node, the 750-333 provides a scalable solution for distributed automation systems used in industrial machinery, process control and factory automation environments. :contentReference
Fieldbus couplers provide the communication interface between distributed I/O modules and central automation controllers. The WAGO 750-333 allows sensors, actuators and control devices connected to WAGO I/O modules to communicate with PLC systems over the PROFIBUS network.
Within the WAGO I/O System architecture, the coupler automatically constructs the process image of connected modules and maps all signals to the PROFIBUS network. This allows flexible system expansion without modifying the existing control application. :contentReference

It connects the WAGO I/O System 750/753 to a PROFIBUS DP network and manages communication between the PLC and connected I/O modules.
The coupler supports up to 63 I/O modules within a single distributed I/O node.
The PROFIBUS interface supports speeds from 9.6 kBd up to 12 MBd.
Yes. The coupler supports mixed configurations of digital and analogue modules connected to the WAGO I/O system.
The coupler is installed at the start of a WAGO I/O node on a DIN rail inside a PLC control cabinet or distributed automation system.
WAGO fieldbus couplers are widely used by automation engineers and machine builders to integrate distributed I/O modules into industrial control networks.
