NX-ECC201 Omron EtherCAT Coupler

The Omron ECC201 is a high-speed EtherCAT Coupler Unit designed for use in NX-series distributed I/O systems. This coupler acts as the interface between an EtherCAT master (e.g., NJ/NX/NY-series controllers) and up to 63 NX I/O units, enabling high-performance, real-time control across machine or plant-wide networks. Built for maximum flexibility, the unit supports task-period prioritized refreshing, timestamp-based I/O, and fast 1 µs I/O jitter, making it ideal for time-critical applications.

With 10 A I/O power handling, USB programming port, and a removable screwless terminal block, the NX-ECC203 offers reliable, compact connectivity for EtherCAT-based control systems.
