NX-series High-speed Analog Input Unit


Simultaneous sampling of 4 channels with sampling times down to 5 μs

High-speed analog inspection with PLC system —No special devices and no PC required

Improving quality in parts inspections requires as detailed analog data as possible. Most automotive and other manufacturers are using PC and special measuring devices such as data loggers for measurements.
Being among the first to work on IoT at manufacturing sites, Omron now offers the High-speed Analog Input Unit that can reliably, precisely, and easily acquire synchronized analog data. It will help you improve quality.


Industry's fastest*1 sampling speed of 5 μs to catch every minute change

Conventional PLC

NX-HAD[][][] 特長 4

Some data could not be obtained when an error occurred


NX-HAD[][][] 特長 5

Sampling as fast as every 5 μs catches all changes in behavior

Industry's fastest sampling speed*1: Same speed*2 regardless of the number of channels

Conventional PLC

Sampling period becomes longer as data is obtained from multiple channels
