NX-ECC202 NX Series EtherCAT Coupler Unit 2 Ports 10A | Omron

The Original New Omron NX-ECC202 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. Supporting a communications cycle from 250 to 4,000 μs and delivering a maximum I/O power supply current of 10 A, it meets the demands of high‑performance distributed I/O applications. The coupler features a USB port for configuration via Sysmac Studio and is delivered with an end cover, making it suitable for machine automation, factory integration, and real‑time control systems.
