ABB 3BSE008514R1 Output Relay

ABB 3BSE008514R1, also known as the DO820 digital output relay, is an eight-channel NO relay module for ABB's S800 I/O family used in Advant/800xA automation systems. It provides eight normally open outputs that switch external loads under the control of the S800 controller. Each channel is rated for up to 2 A and supports a load voltage of 5 to 250 V AC/DC. The module is designed for plug-in installation in ABB IO racks, enabling scalable digital output expansion for industrial automation tasks. Typical applications include driving solenoids, contactors, indicator lamps, valves, and other discrete actuators in process control and manufacturing environments.
