The WAGO 750-347 is an ECO-class CANopen Fieldbus Coupler belonging to the modular WAGO I/O System 750. It acts as a CANopen slave node, linking modular I/O expansion slices (both digital and analog) directly to a master Programmable Logic Controller (PLC) or Human Machine Interface (HMI) over a CANopen industrial network.

• Network Protocol: CANopen communication conforming to DS-301 V4.1 and DS-401 V2.0 profiles. 
• Module Capacity: Supports up to 64 I/O modules per node via automatic local module detection. 
• Process Image Size: Manages a maximum process image width of 32 bytes for inputs and 32 bytes for outputs. 
• Baud Rate: Hardware adjustable from 10 kBd to 1 MBd using integrated DIP switches. 
• Node ID Configuration: Address ranges are quickly configured via local DIP switches. 
• Electrical & Environmental: Operates on a standard 24VDC system supply, mounts securely to standard DIN rails, uses a spring terminal termination style, and carries an IP20 ingress protection rating. 
• Diagnostic Indicators: Front-facing LEDs report immediate status for parameters like STOP, RUN, I/O connection, and TX/RX data overflows
