DO801-EA 3BSE020510R2 Spare Part

The ABB DO801-eA (3BSE020510R2) is a 16-channel digital output module from the S800/S800L I/O family, designed for the ABB System 800xA, AC 800M, and Freelance distributed control systems (DCS). Its core function is to convert logic commands from the controller into 24V DC switching signals to drive field devices such as relays, solenoid valves, indicator lamps, and actuators. With its source-type outputs, built-in short-circuit protection, and compact design, this module is a reliable solution for discrete output applications.
