The Omron NX-AD2603 Machine Automation Controller Analog Input Unit provides 2 voltage input channels for precise measurement in industrial machine-control systems. It accepts -10 to +10 V single-ended analog signals and provides 1/8000 resolution for converting field-level voltage signals into controller data. The module offers ±0.2% full-scale accuracy and a conversion time of 250 μs per point, together with a minimum input impedance of 1 MΩ. Free-Run refreshing supports continuous acquisition of analog values for monitoring and control applications. The NX-AD2603 combines voltage measurement with responsive analog conversion within the PLC analog input range supporting Omron machine control systems.
