WAGO 750-348 ECO CANopen Fieldbus Coupler, D-sub 9-pin, 24 VDC, DIN-rail, Grey

Auto-baud detection from 10 kbit/s to 1 Mbit/s makes the WAGO 750-348 ECO a standout CANopen slave coupler, eliminating manual configuration and ensuring reliable communication even in electrically noisy environments. This fieldbus coupler acts as the gateway between a CANopen network and WAGO's 750-series I/O system, supporting up to 64 digital, analog, or special function modules on a single node.

Overview

The WAGO 750-348 ECO features a standard D-sub 9-pin male interface and operates on 24 VDC system and field supplies (18–30 VDC range). It mounts directly onto a 35 mm DIN rail and provides full galvanic isolation between system and field, protecting connected electronics from interference. Its compact polycarbonate housing is rated IP20 for control cabinet use.

What stands out

• Auto-baud detection from 10 kbit/s to 1 Mbit/s simplifies network setup and prevents errors.
• Supports up to 64 I/O modules for scalable automation solutions.
