Overview

The ABB DO880 is a robust digital output module within the S800 I/O family, engineered for high-performance control in distributed automation systems. It features 16 current-sourcing outputs grouped in one isolated block, each capable of delivering up to 0.5 A continuously. This module is ideal for controlling solenoids, relays, indicator lights, and other low-power devices in both single and redundant configurations.

Moreover, the DO880 includes advanced on-board diagnostics such as loop monitoring, short/open load supervision, and output switch diagnostics without pulsing. In addition, its degraded mode support ensures safe operation for normally energized channels during fault conditions. Therefore, it’s a preferred choice for mission-critical applications requiring reliability and intelligent fault handling.

Technical Data

Typical Applications

Factory Automation

Controls actuators, solenoids, and indicator lights in assembly and packaging lines.

Process Control Systems

Manages digital outputs for valves, pumps, and alarms in chemical and water treatment plants.

Power Generation Facilities

Interfaces with control relays and status indicators in turbine and boiler systems.

Material Handling Systems

Example:
In a bottling plant, the DO880 can trigger solenoid valves and signal lights with precise timing and fault detection, improving throughput and reducing downtime.

FAQ

Q: Can the DO880 be used in redundant configurations?
A: Yes, it supports both single and redundant setups for enhanced reliability.

Q: What happens during a channel fault?
A: The module enters degraded mode for normally energized channels and provides diagnostic feedback.

Q: Is it compatible with other S800 I/O modules?
A: Absolutely. It integrates seamlessly within the S800 I/O system architecture.

Q: What kind of devices can it control?
A: It’s suitable for solenoids, relays, small motors, and indicator lights.

Q: Is configuration software required?
A: Yes, ABB configuration tools are used to set diagnostic thresholds and channel behavior.
