The Omron NX-AD4203 Machine Automation Controller Analog Input Unit measures 2 single-ended 4 to 20 mA current signals for industrial monitoring and control. Analog values are converted at 1/8000 resolution with ±0.2% overall accuracy and a 250 μs per-point conversion time. This combination supports stable acquisition of current signals from compatible field instrumentation used by the controller for machine or process functions. The NX-AD4203 provides a compact current-measurement option within modular NX control architectures. For systems requiring different analog signal types or channel arrangements, the PLC analog input range provides additional choices across Omron machine automation.
