Why Choose the WAGO 750-304 INTERBUS Fieldbus Coupler?
The WAGO 750-304 is an INTERBUS fieldbus coupler designed to connect the modular WAGO I/O System 750 to an INTERBUS network. Acting as the communication interface between field devices and the automation controller, the coupler manages all connected I/O modules and transfers process data between the field level and the control system.
The coupler automatically detects and configures connected digital, analogue and specialty I/O modules, creating a local process image that represents the system’s inputs and outputs. This process image is then transmitted over the INTERBUS network to the PLC or control system for monitoring and control. :contentReference
Supporting up to 64 I/O modules per node and up to 4096 I/O points, the 750-304 provides a scalable solution for industrial automation, machine control and distributed I/O installations. :contentReference

Industrial Automation Fieldbus Communication
Fieldbus couplers act as the central communication interface between distributed I/O modules and automation controllers. The WAGO 750-304 connects field-level devices to an INTERBUS network, enabling real-time exchange of process data between sensors, actuators and PLC systems.
Within the WAGO I/O System 750 architecture, the coupler automatically manages the data flow of connected modules. Digital signals are transmitted bit-by-bit while analogue signals are transferred word-by-word, allowing mixed module configurations within a single distributed I/O node. :contentReference
Typical Applications
- Distributed PLC I/O systems using INTERBUS networks.
- Industrial machine automation.
- Factory automation and production equipment.
- Process monitoring and control systems.
- Integration of digital and analogue field devices.
