Omron NX-AD3204 Analog Input Unit

The NX-AD3204 is a high-speed analog input module from Omron’s NX-series, designed for precise current signal acquisition in distributed control systems. Featuring 4 differential analog input channels with a 4–20 mA range, the unit delivers fast signal conversion at 250 µs per channel and 13-bit resolution, making it ideal for high-speed monitoring and control applications.

This ultra-compact 12 mm wide module uses screwless push-in terminals for quick installation, and integrates seamlessly with NX I/O Bus systems, including those used in Sysmac NJ/NX series controllers.
