TheABB DO828 (3BSE069055R2)is a superior-density digital output solution within the S800 I/O family. Engineered for flexibility and safety, this module provides16 individually isolated relay channels. Its robust design allows for the control of a wide range of field devices, handling up to 250V AC or 125V DC. Whether you are managing complex power distribution or simple motor control, the DO828 delivers the electrical isolation necessary to protect your control system from field-side interference and ground loops.
Core Performance Features
Total Channel Independence:Every one of the 16 channels is individually isolated, allowing you to mix different voltage sources and phases on a single module without risk of cross-talk.
Wide-Range Switching:Rated for2A per channel, it reliably switches voltages up to250V AC and 125V DC, making it suitable for both logic signals and heavy-duty actuators.
Extreme Temperature Resilience:Built for the toughest environments, operating flawlessly from-40°C to +70°C.
Enhanced Safety Ratings:Features a 2000V AC dielectric test voltage and a high IP67-rated protection profile, ensuring longevity in high-humidity or contaminated industrial settings.
Comprehensive Protection:Integrated circuitry guards against overvoltage, overcurrent, and short circuits, protecting both the module and the connected controller.
