💡 Product Description

The 750-338 CANopen Fieldbus Coupler connects WAGO’s modular I/O system directly to a CANopen network, enabling seamless integration of digital and analog signals, as well as complex sensor and actuator systems. This unit serves as a communication gateway, automatically detecting connected I/O modules and mapping them to the process image of the network controller.

Its compact design and high modular scalability make it ideal for distributed control architectures in marine, process, and factory automation. The coupler includes a built-in end module set, ensuring correct bus termination and stable operation within multi-node networks.

The integrated status LEDs provide immediate visual diagnostics for power, communication, and system health. Configuration is simplified via rotary switches for node address assignment, eliminating the need for complex software setup during installation.

With its high EMC resistance and rugged housing, the 750-338 ensures reliability in harsh industrial environments. It supports both standard and vendor-specific CANopen objects, offering flexibility for OEM and system integrator applications.


🧰 Installation & Maintenance

  • Mount the coupler on a DIN rail (EN 60715) before connecting power and fieldbus cables.
  • Ensure the CANopen bus termination is properly configured at the last node.
  • Maintain clean and tight DSUB connections to prevent signal loss.
  • Regularly inspect LED indicators to monitor communication and system health.
