ABB AO610 3BHT300008R1 Analog Output Module

The ABB AO610 3BHT300008R1 Analog Output Module is an industrial-grade analog output module engineered for use with the ABB Advant Controller 410 Series and the Advant Master DCS system. It is designed to deliver precise analog current signals to field actuators and control devices in a wide range of industrial automation systems.

The AO610 provides 8 independent analog current outputs, each capable of delivering a 4 to 20 mA output signal. These outputs are electrically isolated from the system and from each other, ensuring signal integrity and system protection. The module is known for its robust signal quality, long-term stability, and high-resolution conversion, making it highly reliable for continuous process control environments such as refineries, power plants, chemical factories, and water treatment facilities.

Its rugged construction, DIN rail mounting design, and compatibility with ABB’s legacy control platforms make it a long-standing choice in industries requiring proven, long-lifecycle automation components.
