Overview

DO880 (3BSE028602R1) is a high-integrity digital output module designed by ABB for the ABB 

Ability™ System 800xA® S800 I/O platform.

DO880 (3BSE028602R1) features 16 channels of 24 V DC current-sourcing outputs.

DO880 (3BSE028602R1) supports both single and redundant configurations for critical industrial 

automation applications.

DO880 (3BSE028602R1) is engineered with advanced protection, diagnostics, and safety certifications.

DO880 (3BSE028602R1) delivers reliable performance in harsh and mission-critical environments.

Core Functionality

●16 Digital Output Channels: Provides 16 current-sourcing channels (24 V DC, 0.5 A maximum 

continuous current per channel) in one isolated group, enabling high-density I/O integration.

●Redundant & Single Configurations: Flexible deployment as a standalone module or in redundant 

setups to meet high-availability requirements.

●Comprehensive Protection: Each channel includes current limiting (short-circuit proof), over-

temperature protection, EMC shielding, and inductive load suppression for enhanced durability.

●Advanced Diagnostics:

On-board diagnostics for output switches (no pulsing required) and internal circuitry.

Front-panel LEDs (Fault, Run, Warning) and channel-specific status/error indicators for real-time 

monitoring.

Supervision of short and open loads with configurable loop resistance limits (50 Ω to 2 kΩ).

●Safety & Reliability:

Certified for SIL3 (IEC 61508) and Category 4 (EN 954-1) for high-integrity applications.

Fault tolerance of 1 (IEC 61508) for output drivers; normally de-energized (ND) systems retain control 

despite driver errors.

Degraded mode support (for normally energized channels, available from DO880 PR:G) to maintain 

partial functionality during faults.
