Omron EtherCAT Coupler Unit NX-ECC203

Product Name: EtherCAT Coupler Unit

Communication Cycle: 125–10000 μs (configurable via master)

NX Unit Power Consumption: 1.25 W or less

Max. I/O Power Supply Current: 10 A

Direct Use: Not applicable (requires an EtherCAT master for configuration and operation)

The NX-ECC203 is an advanced coupler unit designed to connect Omron’s NX-series I/O modules to an EtherCAT network. It enables high-speed, deterministic data exchange with communication cycles ranging from 125 microseconds to 10 milliseconds, making it suitable for applications requiring precise real-time control, such as motion control, packaging, and assembly systems. The unit consumes minimal power (1.25 W or less) for its internal NX bus, while supporting up to 10 A of I/O power current to drive connected modules and field devices. It is not intended for standalone use; instead, it must be integrated with an EtherCAT master controller, such as an NJ/NX-series machine automation controller or a compatible industrial PC. The coupler supports hot-swap of NX units (when power is off) and provides diagnostics via EtherCAT network status LEDs and process data objects. With its compact design and robust performance, the NX-ECC203 offers a flexible and scalable solution for distributed I/O architectures in modern industrial automation systems.
