ABB DO810 Digital Output Module

1. General Overview

The ABB DO810 is a Digital Output Module designed for use in ABB’s AC 800M controller series. It provides reliable, fast, and isolated digital output signals for controlling field devices such as solenoids, relays, contactors, and indicator lamps. Known for its durability and precision, the DO810 is widely used in distributed control systems (DCS) across power, chemical, and manufacturing industries where consistent performance and system safety are vital.

2. Technical Specifications (Descriptive Format)

The DO810 module provides 16 individually isolated digital output channels, each capable of sourcing 24 V DC with a maximum current of 0.5 A per channel. It is designed for high-output switching reliability and includes built-in current limiting and short-circuit protection.

Each channel supports status feedback, enabling the controller to monitor the health and activity of connected devices in real time. Diagnostic LEDs located on the front panel indicate the ON/OFF state of each output channel and the overall module status, simplifying maintenance and troubleshooting.

The module operates from a 24 V DC system supply, with typical power consumption around 6 W. It can function within an ambient temperature range of 0°C to +55°C, with a storage tolerance of –40°C to +70°C. The unit connects directly to ABB’s ModuleBus via a baseplate, facilitating seamless integration within AC 800M systems.

3. Design and Construction

The DO810 features a compact and modular enclosure, optimized for DIN-rail or baseplate mounting. Its design includes an electronic protection layer for each output channel, ensuring fault isolation without affecting other outputs.
The internal circuitry incorporates optocouplers for galvanic isolation between the field and logic sides, preventing electrical interference. The plug-in terminal block structure allows quick connection and disconnection during installation or replacement.
