Product Overview
The ABB 3BSE028588R1, designated as the DO880-1, is a high-performance 16-channel digital output module engineered for ABB’s System 800xA distributed control platform as part of the S800 I/O family. This versatile output module serves as the critical interface between the control system and field actuators, converting digital control signals into reliable 24V DC outputs that drive valves, relays, contactors, motors, and indicator lights across a wide range of industrial automation applications. The ABB DO880-1 is designed for both single and redundant configurations, providing the flexibility to match the availability requirements of any process control application—from standard production line automation to safety-critical functions.
As a member of the S800 I/O series, the ABB 3BSE028588R1 benefits from ABB’s decades of experience in distributed control systems, incorporating advanced diagnostic capabilities and robust protection features that ensure long-term reliability in demanding industrial environments. Each of the 16 channels on the ABB DO880-1 features a current-limited and over-temperature protected high-side driver, EMC protection components, inductive load suppression, and a dedicated output state indication LED. An isolation barrier to the Modulebus provides galvanic separation between the field wiring and the control system, protecting sensitive electronics from electrical noise and transient events.
The ABB 3BSE028588R1 carries a SIL3 certification according to IEC 61508 and Category 4 certification according to EN 954-1, making it suitable for use in safety instrumented systems where functional safety is paramount. With its comprehensive onboard diagnostics, loop monitoring capabilities, and support for degraded mode operation, the ABB DO880-1 delivers the performance, reliability, and safety integrity that modern industrial processes demand.
