Description
Product Overview
The ABB DSAO110 is a 4-channel analog output module for ABB’s S800 I/O system, compatible with AC 800M controllers and System 800xA DCS. It converts digital signals from the controller into analog outputs (current/voltage) to drive field devices like valves, drives, or indicators. Key features include hot-swappable design, channel-by-channel diagnostics, and galvanic isolation, making it suitable for precise process control in industrial automation.
Designed with SIL 2 safety integrity level support, the DSAO110 ensures reliable operation in critical applications. Each channel can be configured independently for current or voltage output, and the module integrates with ABB’s Control Builder M software for real-time monitoring and fault handling.

Main Features and Advantages
Flexible Output Configuration:
- Dual Signal Types: Each channel can be set to current (4–20 mA) or voltage (0–10 V) for driving valves, PID controllers, or analog meters.
- Fail-Safe Modes: Configurable fail-safe outputs (maintain last value, go to zero, or pre-defined safe value) in case of power loss or communication failure.
Reliability & Safety:
- Galvanic Isolation: Prevents ground loops and protects against electrical surges (2 kV transient protection), critical in noisy environments.
- SIL 2 Compliance: Meets IEC 61508 standards for safety-critical systems, suitable for emergency shutdown (ESD) or safety instrumented systems (SIS).
Operational Efficiency:
- Hot-Swap Capability: Replace modules without system shutdown, reducing downtime in continuous processes.
- Real-Time Diagnostics: On-board LEDs indicate channel status (output active/fault), and software reports open circuits, short circuits, or out-of-range loads.
System Integration:
- Backplane Communication: Connects to ABB’s S800 I/O backplane via DCON protocol (10 Mbps), enabling fast data transfer from controllers.
- Redundancy Support: Can be part of redundant I/O configurations when paired with ABB’s redundant backplane and controllers.
Application Areas
Process Control:
- Oil & Gas: Controls flow valves, pressure regulators, and motor speeds in pipelines and refineries.
- Chemical Plants: Adjusts reactor agitation speed, temperature setpoints, and dosing pumps for precise process control.
Power & Utilities:
- Substations: Drives analog indicators for voltage/current monitoring, controls transformer tap changers.
- HVAC Systems: Manages damper positions, chiller speeds, and heating element outputs for building automation.
Manufacturing:
- Food & Beverage: Controls filling machine pressures, pasteurizer temperatures, and conveyor speeds (IP65 enclosures optional).
- Paper Mills: Adjusts roll tension, pulp flow rates, and drying cylinder temperatures for quality control.

Installation & Maintenance
Installation:
- Mounting: Insert into S800 I/O rack slot, secure with retaining clip.
- Wiring: Connect field devices to TB841 terminal block (ensure correct polarity for voltage outputs, proper load resistance for current outputs).
- Configuration: Use Control Builder M to set output type, scaling, fail-safe mode, and alarm thresholds per channel.
Maintenance:
- Periodic Calibration: Verify output accuracy using a multimeter or signal calibrator (recommended annually).
- Fault Handling: Replace faulty modules without powering down the system (hot-swap).
- Firmware Updates: Download via ABB’s Service Portal to ensure compatibility with controller firmware.
Product Guarantee
New DSAO110 modules include a 1–2 year warranty, covering defects in materials and workmanship. Refurbished units come with a 90-day warranty and undergo testing for output accuracy and isolation integrity. ABB’s global service network provides technical support, and spare parts are typically available for 10+ years post-production.
For applications requiring hazardous area certification, consult ABB’s documentation to ensure compliance (e.g., ATEX, IECEx). The DSAO110 is ideal for systems needing precise analog output control with built-in safety and diagnostic features, balancing performance and reliability in industrial automation setups.
