With the new EPX module series, Beckhoff offers a compact option for Ex i signal acquisition from zones 0/20, 1/21 and Div. 1 as an addition to the wide range of EtherCAT Box modules. With robust IP67 protection, they enable direct and decentralized installation on machines and systems, even in harsh environments. This results in numerous advantages in all areas with explosion protection requirements, both in processing plants and in discrete manufacturing applications. Interface options are available for the popular HART, NAMUR and FDT/DTM standards.

As a robust alternative to IP20 solutions with additional enclosures, the IP67-rated EPX modules enable reliable data collection, even in hazardous areas where no control cabinet or terminal box can or should be installed. The extremely compact modular design leads to significant space savings.
Furthermore, the previously required safety barriers are no longer necessary, which saves space and reduces costs. Additional advantages of the new EtherCAT Box modules are their simple commissioning, avoidance of errors due to incorrect contact assignments and system modularization facilitated by on-site signal acquisition.
The EPX series initially comprises three modules with four or eight input channels:
