OMRON NX-AD3604 4-Point Analog Input Unit for NX Series PLC

The OMRON NX-AD3604 (NX-AD3604) is a four-point analog input unit designed for use with OMRON programmable logic controller systems. As part of an automation control architecture, this module provides analog-to-digital signal conversion to interface standard analog field devices with the PLC processing system. It features four input points supporting a current input range of 0 to 20 mA, with an input resolution of 1/8000 to convert analog signals accurately into digital data for the controller. In industrial automation environments, the unit is utilized for acquiring process signals from sensors, transmitters, and current-loop measurement instruments. By capturing 0 to 20 mA analog feedback across its four points, it allows the programmable logic controller to monitor process parameters such as flow, level, pressure, and position. The module is suited for machine control systems, process monitoring, and factory automation applications that require reliable analog input acquisition within an OMRON PLC installation.
