ABB DO880 3BSE028602R1

1. Overview

ABB DO880 3BSE028602R1 is a 24 V DC digital output module designed for industrial automation platforms such as ABB 800xA®, S800, and Advant Controller 400 series. Equipped with 16 independent channels, it can reliably drive field devices in either standalone or redundant configurations.

2. Specifications

• Model/Ordering Code: DO880 / 3BSE028602R1
• Number of Channels: 16 channels
• Operating Voltage: 24 V DC (19.2 - 32 V)
• Maximum Continuous Output Current per Channel: 0.5 A
• Output Type: Current source with current limiting and over-temperature protection
• Mounting Method: DIN rail modular mounting
• Environmental Conditions: Operating temperature ranging from -40 °C to +70 °C, IP20 protection class
• Dimensions/Weight: Approximately 112 mm × 90 mm × 103 mm, weighing around 0.3 kg

3. Product Features

• High Reliability: Supports redundant or standalone configurations, with short-circuit/open-circuit monitoring, over-temperature protection, and output diagnostic functions.
• Isolated Outputs: Each channel features independent photoelectric isolation, reducing interference and enhancing safety.
• Fast Response: Boasts a maximum switching frequency of 10 kHz, ideal for high-speed control scenarios.
• Strong Compatibility: Supports multiple communication interfaces including Modbus RTU and Modulebus, enabling seamless integration with multiple series of ABB PLCs.
• Compact Design: The modular structure facilitates on-site installation, maintenance, and replacement.

4. Structure and Components

• High-Side Drivers: Each channel is equipped with a high-side driver with current limiting and over-temperature protection.
• EMC Protection Components: Suppress electromagnetic interference to ensure signal integrity.
• Inductive Load Suppression Circuits: Compatible with inductive loads such as relays and valves.
• Status Indicator LEDs: Display the output status of each channel in real time.
• Module Bus Isolation Barrier: Achieves electrical isolation between the internal and external parts of the module.

5. Application Fields

• Process Control: Drives on-site actuators like valves, relays, and indicator lights.
• Manufacturing Automation: Applied in machine safety circuits, alarm systems, and equipment interlocking.
• Power Systems: Used for relay protection, switch control, and monitoring circuits.
• Other Industrial Automation Scenarios: Suitable for any application requiring 24 V DC digital outputs, especially in critical systems that demand redundant reliability.

6. Installation and Maintenance

Installation

Insert the module into the DIN rail slot and secure it with screws; ensure the supply voltage is within the range of 19.2 - 32 V.

Wiring

Connect the 24 V DC power supply to the module's power terminal in accordance with the markings in the module manual, and connect loads (such as relays and valves) to the output terminals. Note that the maximum current limit of 0.5 A per channel must be observed.

Commissioning

Perform channel mapping and parameter configuration via PLC programming software (e.g., ABB Automation Builder), and check the output status using the status indicator LEDs.

Maintenance

Regularly inspect the tightness of wiring and whether there is dust or corrosion on the module surface; before replacing the module, cut off the power supply and record the original configuration for quick restoration.
