Beckhoff Extends Decentralized Automation with High-Power MX-System Additions
Beckhoff Automation has scaled up its modular MX-System platform, introducing 3-row baseplates and larger size 3 function modules designed to eliminate control enclosures on heavy-duty machinery. By boosting physical layout area and expanding data routing channels, this portfolio expansion allows manufacturing facilities to transition complex, high-draw equipment toward an IP67-rated decentralized architecture, effectively cutting engineering footprints and streamlining floor-level field installation times.
The latest iteration of the MX-System platform addresses a critical scaling bottleneck for large-scale production machinery that traditionally relies on bulky, floor-standing electrical enclosures. Industrial engineers can now deploy a cabinet-free automation framework across wider footprints by leveraging the newly engineered 3-row baseplates. These components serve as robust backplanes, providing the essential infrastructure to interconnect high-density control electronics directly on the machine frame. This shift away from traditional centralized enclosures fundamentally alters hardware deployment, reducing complex wiring looms, eliminating dedicated climate control units, and accelerating commissioning cycles through standardized plug-and-play installation.
A primary driver behind this product line expansion is the introduction of the larger size 3 function modules. These units are built to manage demanding power distribution tasks and heavy electrical loads that were previously beyond the scope of compact, machine-mounted hardware. The new modules support substantial power combinations, including power supply modules delivering up to 63 A, servo controllers rated at 28 A, and a 600 V DC bus link capable of handling 40 A. Beckhoff has indicated that future hardware rollouts will further extend these capabilities, introducing options to switch alternating current loads up to 16 A and expanding main feed-in capacities to 125 A.
From a structural topology standpoint, the 3-row baseplates act as a primary distribution node within a hybrid star and daisy-chain network configuration. This allows system integrators to position the larger baseplate at the heart of the machine's electrical layout, linking it directly to existing 1-row and 2-row variants situated closer to localized sensors and actuators. Additionally, the mechanical flexibility of the framework allows operators to populate the 3-row footprint with smaller size 1 and size 2 modules, offering an optimized, low-profile footprint for compact machinery with dense input/output counts. By securing an IP67 ingress protection rating, the entire assembly remains completely dust-tight and resistant to water submersion, ensuring long-term operational reliability in harsh industrial environments without secondary protective housings.
