£435.36
The WAGO 750-838 is a powerful and compact CANopen programmable fieldbus controller designed for industrial automation, machine control and distributed I/O applications. As part of the trusted WAGO-I/O-SYSTEM 750 series, this controller combines PLC functionality, CANopen communication and flexible I/O expansion in a single DIN rail mounted device, making it ideal for decentralised automation architectures.
Designed for OEM machine builders, system integrators and industrial automation engineers, the controller enables local signal processing and intelligent field-level control. By distributing control functions closer to the process, system response times can be improved whilst reducing fieldbus communication traffic.
Featuring integrated CANopen communication up to 1 Mbit/s, a 16-bit processor, 128 KB program memory and support for the complete WAGO-I/O-SYSTEM 750 module range, the 750-838 provides a reliable and cost-effective solution for demanding industrial automation projects.
The WAGO 750-838 combines control functionality, I/O interface capabilities and CANopen communication in a single compact platform. Engineers can directly access fieldbus and I/O data, enabling efficient implementation of decentralised machine control and process automation systems.
Its support for IEC 61131-3 programming languages allows the controller to be integrated into a wide range of industrial automation environments. Local processing capabilities help reduce network load whilst improving overall system responsiveness and reliability.
