The Omron NX-EC0112 Machine Automation Controller Position Interface Unit provides 1 NPN encoder channel together with 3 NPN external inputs for incremental position feedback. It supports a maximum response frequency of 500 kHz and 24 V input signals for connection with compatible positioning devices. Free-Run, Synchronous I/O, and Task-Period Prioritized refreshing provide different methods for transferring position data to the controller, while 1/1 I/O mapping supports structured data exchange. The NX-EC0112 brings encoder feedback into an NX machine-control architecture for position-related applications. It complements the PLC motion and counting range within Omron motion automation systems.
