WAGO 750-333 PROFIBUS DP Fieldbus Coupler

The WAGO 750-333 is a PROFIBUS DP fieldbus coupler designed for seamless integration of WAGO I/O systems into PROFIBUS DP networks. As a slave device, it enables efficient data exchange between field devices and higher-level control systems, supporting baud rates from 9.6 kbit/s to 12 Mbit/s with automatic detection. This coupler is ideal for industrial automation applications requiring reliable and flexible communication.

Advantages

• Supports up to 64 I/O modules (standard) or 250 with bus extension, providing scalability for various system sizes.
• Auto-detecting baud rate simplifies setup and ensures compatibility with different network speeds.
• Compact DIN-rail mount design saves space in control cabinets.
• Robust isolation (500 V system/field) enhances system reliability and safety.
