ABB DO880 3BSE028602R1 Digital Output Module

Overview

The DO880 (article number 3BSE028602R1) is a high-integrity digital output module designed by ABB 

for the ABB Ability™ System 800xA® S800 I/O platform. It features 16 channels of 24 V DC current-

sourcing outputs, supporting both single and redundant configurations for critical industrial 

automation applications. Engineered with advanced protection, diagnostics, and safety certifications, 

it 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.
