Overview

The ABB DO815 is a digital output module within the S800 I/O family, designed for high-performance distributed control systems. It provides eight current-sourcing digital outputs, grouped into two isolated blocks of four channels each, with built-in protection and diagnostics to ensure safe and reliable operation in harsh industrial environments.

Moreover, the DO815 supports open-load detection, short-circuit protection, and overload monitoring, enhancing system reliability and minimizing maintenance time. In addition, it includes status LEDs and channel-wise error flags for rapid troubleshooting. Therefore, it is widely used in industrial automation, process control, power generation, and infrastructure applications where robust digital output control is required.

Technical Data

Typical Applications

Factory Automation

Controls solenoids, relays, and indicator lights in packaging, assembly, and material handling systems.

Process Control Systems

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

Power Generation

Interfaces with auxiliary systems such as cooling fans, fuel pumps, and status indicators.

Transportation and Infrastructure

Manages signaling and control devices in rail, tunnel, and airport automation systems.

Example:
In a bottling plant, the DO815 can activate pneumatic actuators and signal lights with precise timing and built-in fault detection, improving uptime and reducing manual intervention.

FAQ

Q: How many outputs does the DO815 support?
A: It provides 8 digital outputs, divided into two isolated groups of four channels each.

Q: What kind of protection is included?
A: Each channel includes short-circuit, overload, and open-load protection, along with diagnostic feedback.

Q: Can it be used in redundant systems?
A: Yes, it integrates into redundant S800 I/O configurations for high availability.

Q: What happens during a communication fault?
A: The module can set outputs to a predefined state using the Output Set Point (OSP) feature.
