Wago 750-338 FC Canopen, Dsub

Why Choose the WAGO 750-338 CANopen Fieldbus Coupler?

The WAGO 750-338 is a CANopen fieldbus coupler with D-Sub connection designed to integrate the modular WAGO I/O System 750/753 into CANopen automation networks. Acting as the communication interface between distributed field devices and PLC or industrial controllers, the coupler exchanges process data between connected I/O modules and the CANopen master system. :contentReference

During start-up the coupler automatically detects all connected I/O modules and creates a local process image representing the inputs and outputs of the installed system. Digital signals are transmitted bit-by-bit while analogue and specialty module data are transmitted as words or bytes, enabling efficient communication across distributed industrial control architectures. :contentReference

Designed for scalable automation systems, the coupler supports up to 64 connected I/O modules per node and communicates with the controller using CANopen process data objects (PDOs) and service data objects (SDOs), providing reliable data exchange between sensors, actuators and automation equipment. :contentReference
