NX-ECC201 NX Series EtherCAT Coupler Unit 2 Ports 4A | Omron

The Original New Omron NX-ECC201 is an EtherCAT coupler unit for the NX series I/O system, designed to connect up to 63 NX I/O units to an EtherCAT network as a single slave node. Featuring a 250 μs minimum communications cycle, two RJ45 EtherCAT ports with 100BASE‑TX support, and a maximum I/O power supply current of 4 A, it meets the demands of high‑performance distributed I/O applications. The coupler supports multiple refreshing methods including Free‑Run, Synchronous I/O, Time stamp, and Task period prioritized. It is delivered with an end cover, making it suitable for machine automation, factory integration, and real‑time control systems.
