Product Description
ABB ANK31 Analog Input/Output Module
Product Overview
- The ABB ANK31 is an Analog Input/Output Module designed for use in ABB’s Advant OCS (Open Control System) or Master systems, particularly within distributed control systems (DCS) for industrial automation. This module facilitates the acquisition and processing of analog signals from field devices (e.g., sensors, transmitters) and provides analog outputs to actuators or other devices. It is commonly used in industries such as power generation, oil and gas, chemical processing, and pulp and paper for precise process control and monitoring. The ANK31 is known for its reliability, flexibility, and compatibility with ABB’s legacy automation platforms.
