Product Introduction
The ABB AO810 3BSE008522R1 is a high-performance Analog Output Module designed for use within the ABB AC 800M control system, part of the 800xA process automation platform. It serves as an interface for analog signal generation, capable of outputting 8 individual channels of analog current signals (0/4–20 mA) to field devices such as actuators, control valves, and other process instrumentation.
Engineered with precision and reliability, the AO810 is equipped with HART (Highway Addressable Remote Transducer) protocol compatibility, allowing for advanced field device communication and diagnostics. Each output channel is galvanically isolated and features current limiting, protection against short circuits, and diagnostic capabilities that enhance system uptime and reliability in demanding industrial applications.
Built to meet the needs of continuous process industries, this module is commonly used in applications where precise analog control is required, including chemical, oil and gas, pulp and paper, metals, power generation, and water treatment facilities.
