ABB designates AI820 as an Analog Input Module associated with the Advant 800xA control platform.
In day-to-day system operation, digital input hardware creates the path from field-level status signals to control logic, allowing the system to evaluate operating conditions and respond through configured sequences or protective actions. This helps preserve the function assigned to the installed control node.
ABB Advant and System 800xA environments combine control, I/O, communication, and operator resources. This product supports the hardware function identified by its description within the installed system. Installation should follow the control node's approved hardware records.
Country of origin is listed as Estonia.
