The Omron NX-AD3204 Machine Automation Controller Analog Input Unit is configured with 2 differential channels for precision 4 to 20 mA current measurement. Signals are converted at 1/30000 resolution with ±0.1% overall accuracy, while a 10 μs per-point conversion cycle enables rapid acquisition. Synchronous I/O refreshing can coordinate measurements with controller execution, whereas Free-Run refreshing supports continuous signal updates. These characteristics distinguish the NX-AD3204 when higher-resolution differential current acquisition is required. Its measurement capability complements the high-resolution PLC analog input range available for Omron machine control systems.
