DO828 ABB | 3BSE069055R1 Isolated 16-Channel Relay Output

Product Description

Product Overview

The DO828 (Part Number: 3BSE069055R1) is a high-density, 16-channel relay output module engineered for the ABB S800 I/O system. This module provides a robust interface between the control system and high-power field devices, supporting both AC and DC switching. Each channel is individually isolated, ensuring superior electrical separation and protecting the controller backplane from field-side transients. The DO828 is capable of handling up to 250V AC or 125V DC, making it an ideal choice for controlling interposing relays, contactors, and high-wattage solenoid valves in complex industrial automation environments like Power Generation, Oil & Gas, and Chemical processing.
