The Omron NX-AD2608 Machine Automation Controller Analog Input Unit accepts 4 single-ended -10 to +10 V signals for multi-channel voltage acquisition. Each input is converted at 1/8000 resolution with ±0.2% overall accuracy and a conversion time of 250 μs per point. Free-Run refreshing continuously updates measured values for controller processing during machine operation. With 4 input channels in one module, the NX-AD2608 expands the voltage-measurement capacity of an NX control system without requiring an individual module for every signal. It forms part of the PLC analog expansion range used with Omron industrial automation equipment.
