DO820 3BSE008514R1 ABB 8-channel 230 V AC/DC Relay Output Module IP20 3A

The ABB DO820 (Order Code: 3BSE008514R1) is a high-density digital output module designed for the AC 500 PLC platform and integrated into ABB’s System 800xA distributed control system. This robust I/O module provides 16 relay-based digital outputs with change-over (SPDT) contacts, enabling direct switching of AC/DC loads such as solenoids, contactors, indicator lamps, and small motors—without requiring external relays.

Engineered for reliability in demanding industrial environments, the DO820 supports voltages up to 250 V AC / 125 V DC and delivers galvanic isolation between field circuits and the internal logic, ensuring safe and stable operation in applications ranging from water treatment and energy distribution to manufacturing and building automation. With plug-and-play integration into the AC 500 I/O bus and full support in Automation Builder and Control Builder M, it simplifies engineering, reduces panel space, and enhances system maintainability.
