DO820 Digital Output Modules | ABB 3BSE008514R1

ABB - DO820 3BSE008514R1

Key Functional Highlights:

Supports 8 isolated relay channels for high-voltage control at 230 V a.c./d.c. (rated range: 5 - 250 V)

Each channel delivers 3 A max current and features LED output status indicators

OSP (Output Set Point) functionality ensures safe failover by reverting to predefined output states upon fault detection

Advanced relay supervision monitors the internal 24 V power via ModuleBus and triggers warnings if anomalies are detected

Output relays are optically isolated for 2000 V a.c. dielectric protection, ensuring enhanced circuit safety
