NX-ECC202 Omron EtherCAT Coupler Unit for NX Series I/O

The Omron NX-ECC202 is a high-performance EtherCAT coupler unit that connect up to 63 NX I/O modules to an EtherCAT network. Designed for rapid communication and flexible topology, these couplers support Free-Run, Synchronous I/O, and Time Stamp refreshing, with DC Mode cycle times as low as 125 µs.

With robust construction, RJ45 EtherCAT ports, removable screwless terminal blocks, and up to 10 A I/O current support, these modules ensure high-speed data exchange and simplified wiring for modular control architectures.
