Product Overview
The ABB DO880-1 (Part Number: 3BSE028588R1) is a high-performance digital output module that is part of ABB’s S800 I/O series, used widely in ABB’s 800xA Distributed Control System (DCS). The module provides 16 discrete output channels, designed to switch 24 VDC signals to actuate field devices such as relays, contactors, solenoids, and indicator lamps.
This module offers excellent channel diagnostics, short-circuit protection, and field-side isolation, making it a reliable solution for output control in critical industrial processes. The DO880-1 is designed with performance, durability, and flexibility in mind—enabling it to handle demanding applications in power plants, manufacturing, transport, and process automation environments.
It is typically mounted on a terminal base (e.g., TU810V1) and is hot-swappable, meaning it can be replaced without interrupting system operations—supporting high system availability.
