DO820 is identified by ABB as a Digital Output Relay Module within the Advant 800xA family.
For replacement planning, a digital output module converts controller decisions into discrete field commands used for functions such as switching, enabling equipment, annunciation, and actuator control through the appropriate output circuit. The documented module assignment should remain the basis for selection.
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. Connection and configuration should follow the requirements of the platform.
Listed countries of origin are Sweden and China.
