Product Introduction
The ABB DSAO 120 is part of the S100 I/O analog-output family used in ABB Advant process-control installations. Its role is to convert control-system output commands into analog signals for connected equipment. Depending on the installed configuration, these signals may be used for actuator positioning, process setpoints, and other continuous control functions. The associated DSAO 120A board is documented as an 8-channel analog-output board.
Part number 5FSE707630-71 is identified by ABB documentation as a DSAO 120 replacement kit. For maintenance planning, distinguish the kit order number from the board designation: they do not necessarily identify identical physical contents. Confirm the existing board’s marking, installed system configuration, signal types, and required accessories before approving a replacement.

Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
An analog-output fault can appear as a valve-positioning problem, an incorrect drive reference, or a process-control deviation. Replacing the output board without checking the field loop can leave the original fault unresolved. Before changing the module, determine whether the issue originates in the output channel, field wiring, loop power, actuator input, or controller configuration.
Typical Applications
- Analog command outputs in ABB Advant process-control installations.
- Maintenance of S100 I/O hardware in legacy distributed control systems.
- Replacement planning for a failed DSAO 120-family output board or kit.
- Troubleshooting analog control signals connected to actuators and other field devices, where supported by the installed output configuration.
Technical Pitfalls to Avoid
- Confirm the complete order number. Match
5FSE707630-71against the installed hardware records and the replacement-kit documentation. - Check signal type and range. Voltage and current outputs are not interchangeable without confirming the field device’s input requirements and the board’s configuration.
- Verify channel assignments. Record existing channel-to-loop mappings before removing the module. An incorrect mapping can affect several control loops after restart.
- Inspect the field circuit. Check for open circuits, shorts, incorrect loop power, grounding problems, and actuator input faults before attributing the failure to the board.
- Confirm system compatibility. Check the installed S100 I/O arrangement, controller family, carrier or mounting hardware, and any configuration requirements.
- Test before returning to service. Verify each affected channel against the approved drawings and operating procedure, then confirm the response of the connected field device.

Procurement Note
When sourcing ABB DSAO 120, part number 5FSE707630-71, request confirmation of the exact kit contents, board designation, revision, and applicable system compatibility. Compare the existing module’s nameplate and connector arrangement with the replacement documentation. Confirm channel ranges and calibration requirements against the installed loop drawings. Do not assume that a related DSAO 120 kit is a direct substitute solely because it shares the same family name.
