The Omron NX-AD2204 Machine Automation Controller Analog Input Unit measures 2 differential 4 to 20 mA current signals with 1/30000 resolution. Its ±0.1% overall accuracy supports precise current acquisition, while a 10 μs per-point conversion time enables rapid signal processing. Synchronous I/O refreshing coordinates measurements with controller operation when required, and Free-Run refreshing supports continuous acquisition. Differential inputs distinguish the NX-AD2204 from single-ended current input configurations and support high-resolution measurement requirements. The module extends the high-resolution PLC analog range available within Omron industrial automation systems.
