About ABB DO802 Digital Output Relay Module (3BSE022364R1), S800 I/O system, individual galvanic isolation, high-load process automation control

Manage high-power heavy industrial loads safely with the versatile ABB DO802 Digital Output Relay Module (3BSE022364R1). Specially engineered for seamless integration inside ABB S800 I/O, System 800xA, and Advant distributed control platform architectures, this premium module provides 8 independent, normally open (NO) relay output channels. Built with zero-compromise signal separation, each channel features its own dedicated galvanic isolation barrier, completely blocking high-voltage noise, transients, or inductive kicks from disrupting your sensitive backplane processing logic. Optimized for multi-voltage field arrays, it bridges the gap between field and logic by switching varied load thresholds across a broad 24 V to 230 V AC or DC operating spectrum. The compact module comes equipped with hardware-driven diagnostic logging and per-channel status LEDs for straightforward panel troubleshooting, alongside a hot-swappable connection topology that slashes maintenance downtime. It is the definitive engineering solution for driving heavy duty solenoids, interposing circuit breakers, and motor contactors securely on aggressive manufacturing floors.
