Products Beckhoff EPX module series Ethercat I/OS intrinsic safety
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 IP67 protection, the series enables direct and decentralized installation on machines and systems, even in harsh environments.
This results in numerous advantages in all areas with explosion protection requirements, the company says, both in processing plants and in discrete manufacturing applications.
Interface options are available for the popular HART, NAMUR and FDT/DTM standards.
The EPX series initially comprises three modules with four or eight input channels.
EPX1058 is designed for direct connection of up to eight intrinsically safe NAMUR field devices and records their signals pursuant to IEC 60947-5-6.
EPX3158 supplies a maximum of eight measuring transducers located in the field and transmits their analog 4…20 mA measuring signals, electrically isolated, to the automation device.
EPX3184, which connects up to four intrinsically safe HART-capable field devices, provides information on the state of HART communication via LEDs and signals any communication errors.
