Wago 750-838/021-000 Controller Canopen, M3 Dsub

Why Choose the WAGO 750-838/021-000 CANopen Controller?

The WAGO 750-838/021-000 is a compact CANopen programmable controller designed for decentralised automation systems using the modular WAGO I/O System 750. This DIN-rail PLC integrates fieldbus communication, local control processing and modular I/O connectivity in one device, allowing distributed machine control architectures to be implemented efficiently.

Using the CANopen fieldbus protocol, the controller exchanges data with automation networks while executing local PLC logic. Processing signals locally helps reduce communication load across the network while improving system responsiveness and reliability in industrial environments. :contentReference

The controller supports IEC 61131-3 programming languages and can be programmed using environments such as WAGO-I/O-PRO (CODESYS based). Engineers can access all fieldbus and I/O data within the program environment, enabling flexible automation control for machines, process equipment and distributed I/O installations. :contentReference
