The WAGO 750-303 is a 1st Generation PROFIBUS DP/FMS Fieldbus Coupler designed for the WAGO I/O System 750. It serves as a decentralized slave node that links local digital, analog, and specialty I/O modules directly to a higher-level PLC or control system over a PROFIBUS network.

• Communication Rate: Up to 12 MBaud (12 MBd) for responsive, fast data exchange.
• Module Capacity: Supports up to 64 I/O modules per node.
• Process Image: Automatically maps inputs and outputs into 128-byte input and 128-byte output data zones.
• Supply Voltage: Operates on standard 24 VDC system and field power.
• Mounting & Ingress: Standard 35mm DIN-rail mounting with an IP20 protection rating.
• Diagnostics: Features physical status LEDs for network faults (BF), system run status (RUN), and device diagnostics.
