Omron NX-AD3208 Analog Input Module

The Omron NX-AD3208 is a high-speed, high-resolution analog input module designed for the NX-series I/O system. Featuring four differential current inputs (4 to 20 mA), 15-bit resolution (1:30,000), and ultra-fast 10 µs per channel conversion time, it ensures precise signal acquisition in advanced automation environments.

Its slim 12 mm-wide profile and screwless push-in terminal make it ideal for space-saving control panels in industries like packaging, process automation, or robotics.
