Description
Product Overview
The ABB DSAO130 57120001-FG is an analog output board in ABB’s legacy S100 I/O product family. Its 16 channels convert digital output commands from the controller into analog signals for compatible process equipment. Typical applications include sending reference signals to valve positioners, actuator controls, and other devices that accept voltage or current commands. The documented output ranges are 0–10 V and 0–20 mA, with a published accuracy figure of 0.4%. Actual operation depends on the board configuration, connection unit, field wiring, and controller software.
A significant field consideration is that the DSAO130’s outputs are not galvanically isolated from one another. ABB’s S100 I/O manual also notes that current-output loads must be potentially floating. This matters when connecting instruments with grounded signal returns or when multiple outputs share external reference potentials. Before wiring, verify the signal mode, jumpers, grounding arrangement, load requirements, and applicable connection-unit diagram. The board is not simply a universal 16-channel output card that can be connected without checking the installed configuration.
Procurement requires a further distinction. ABB identifies the DSAO130 as a spare part for Safeguard safety controllers and states that the installed controller’s hardware license number must be supplied when ordering. For other process controllers, ABB points to the DSAO130A together with the DSTA181 connection unit. This is a system-specific compatibility requirement, not merely a naming difference. Match the existing board’s order number and the host controller before selecting a replacement.
Product Introduction
The ABB DSAO130 is a 16-channel analog output board for legacy S100 I/O installations. Its documented voltage and current ranges support analog control signals, but output isolation and controller compatibility must be checked before installation.
For replacement planning, confirm the Safeguard controller’s hardware license number, installed connection unit, output configuration, and field-load grounding. For other process controllers, investigate the DSAO130A and DSTA181 combination rather than assuming the original board is interchangeable.

Frequently Asked Questions
Q1. What is the ABB DSAO130 used for?
It converts controller output values into analog voltage or current signals for compatible field devices. It provides 16 output channels.
Q2. Is the compatible with every ABB Advant controller?
No. ABB identifies this version as a spare for Safeguard safety controllers and requires the installed controller’s hardware license number when ordering. For other process controllers, ABB specifies a DSAO130A with DSTA181 combination.
Q3. Is interchangeable with ?
Do not assume so. The model and ordering codes differ, and ABB specifies the /DSTA181 combination for other process controllers. Confirm the host system and approved configuration before substituting.
Q4. Are the 16 outputs electrically isolated?
No. ABB’s S100 I/O documentation states that the outputs are not galvanically isolated from one another. Check grounding and load-reference requirements before connecting field wiring.
Q5. Can it output a 4–20 mA signal?
The documented range is 0–20 mA. Whether the required 4–20 mA behavior is available through the intended configuration should be verified in the manual and controller application.
Q6. What information is required when ordering?
For the , ABB says the hardware license number of the installed controller must be specified. Also confirm the full order number, connection-unit type, output configuration, and the condition of the supplied board.
Q7. What should be checked on a used or refurbished unit?
Request photographs of the actual board and its label, evidence of functional testing, channel-by-channel test coverage if available, and warranty terms. A visual inspection or power-up check alone does not prove that all 16 outputs meet their specified behavior.
