Product Overview

The NX-AD4208 is an Omron NX-series analog input module providing eight differential current inputs (4-20 mA) designed for panel-mounted installation within NX I/O systems. It supports selectable synchronous or Free-Run refreshing synchronized with NX1P2 CPU or EtherCAT coupler units, and features high resolution (1/30000 full scale), fast conversion (10 µs per point), and integrated isolation between each input and the NX bus. The unit serves precision signal acquisition in process control, motion systems, and quality monitoring networks.
