WAGO 750-338/040-000 CANopen fieldbus coupler for WAGO I/O System 750 XTR with extended temperature range and communication speeds up to 1 Mbit/s.
£478.67
The WAGO 750-338/040-000 is a rugged CANopen fieldbus coupler designed for the WAGO I/O System 750 XTR. It connects distributed I/O modules to CANopen automation networks, enabling reliable communication between sensors, actuators and industrial controllers in demanding environments.
The coupler automatically detects all installed digital, analogue and speciality I/O modules and creates a local process image representing the entire node configuration. Digital signals are transmitted bit-by-bit while analogue values and speciality data are transmitted as words or bytes via CANopen PDOs and SDOs, ensuring efficient process data exchange with the control system. :contentReference
This XTR (Extreme) version is engineered for harsh industrial conditions with enhanced resistance to vibration, shock, electromagnetic interference and environmental stress. With an extended operating temperature range and high EMC immunity, it is ideal for applications in energy infrastructure, transportation systems and outdoor automation installations. :contentReference
Fieldbus couplers provide the communication bridge between distributed I/O modules and central automation controllers. The WAGO 750-338/040-000 enables sensors, actuators and monitoring devices connected to WAGO I/O modules to communicate with PLCs or industrial PCs via the CANopen industrial network.
Within the WAGO I/O System architecture, the coupler automatically maps signals from connected modules into CANopen PDO structures. Digital signals are grouped into bytes while analogue signals are transmitted as words, enabling efficient process data exchange between field devices and the automation controller. :contentReference

It connects the WAGO I/O System 750 XTR to a CANopen network and manages communication between PLC controllers and connected I/O modules.
The coupler supports up to 64 modules within a single distributed I/O node.
The CANopen interface supports communication speeds from 10 kbit/s up to 1 Mbit/s.
The XTR version is designed for harsh environments with extended temperature range, higher EMC immunity and improved vibration resistance.
The coupler is mounted at the beginning of a WAGO I/O node on a DIN rail inside PLC control cabinets or distributed automation systems.
WAGO CANopen fieldbus couplers are widely used by automation engineers and system integrators to connect distributed I/O modules to industrial CANopen control networks.
