Product Overview
The ABB DO810 is a 16-channel digital output module designed for 24 V DC current sourcing applications. Part of the S800 I/O family, this module delivers reliable performance in demanding industrial environments. Each channel provides up to 0.5 A continuous output current with robust protection against short circuits, overvoltage, and overtemperature. The DO810 is engineered to meet the needs of process control systems where uptime and safety are critical.
Key Features & Benefits
-
16 channels for 24 V DC current sourcing outputs
-
2 isolated groups of 8 channels with process voltage supervision
-
Output status indicators for easy diagnostics
-
OSP (Output State Preset) sets outputs to a predetermined state upon error detection
-
Short-circuit protection to ground and 30 V
- Over-voltage and over-temperature protection
- Each output channel includes a high-side driver, EMC protection, inductive load suppression, LED status indication, and optical isolation barrier
This module provides channel error signals via the ModuleBus if the process voltage disappears, allowing for proactive maintenance and reduced downtime.

Industry Applications
The ABB DO810 is ideal for controlling solenoid valves, motor contactors, and indicator lamps in process automation. In a typical chemical plant, the DO810 can manage valve actuators in a batch process, where its isolated groups allow safe operation of different voltage zones. Its fast error detection via process voltage supervision helps prevent costly production halts.
Installation & Setup
Mount the ABB DO810 on a standard DIN rail within an S800 I/O system. Ensure proper grounding and observe the maximum field cable length of 600 meters. Use the keying code AA to avoid incorrect insertion into the mounting unit. Connect the ModuleBus cable securely and verify that the process voltage is within the specified range (12–32 V DC) before powering up.
Maintenance & Reliability
Regularly inspect the front LEDs for fault (F), run (R), warning (W), and OSP status. Check that the ambient temperature stays within 0 to +55 °C (32–131 °F) for optimal performance. The DO810's built-in short-circuit and over-temperature protection reduce the risk of damage, minimizing maintenance costs and extending service life.
Compatibility & Integration
This module works with ABB S800 I/O systems and is compatible with MTU TU810, TU812, TU814, and TU830. It supports ModuleBus communication for diagnostics and control. The DO810 is CE marked and certified for hazardous locations (ATEX Zone 2, cULus), making it suitable for a wide range of industrial environments.
