More Information

Overview Manuals Output Channels S100 Integration OSP Handling Hardware Identity

Features:

  • Provides eight independent analog output channels on one S100 I/O board.
  • Adds OSP control to the DSAO 120A output-board configuration.
  • Remains identified as supported S100 I/O in the documented Advant Master integration path.
ABB DSAO120A 3BSE018293R1 carries controller output values from the S100 I/O interface to eight analog field channels.

The A-version is distinguished by OSP control, so its behavior and ordering identity must not be reduced to the base DSAO 120 designation.

Rack compatibility is established through the S100 I/O architecture and its supported Advant Master integration, not by transferring specifications from nearby DSAO models.

The ABB DSAO120A 3BSE018293R1 Eight-Channel Analog Output Board with OSP Control may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

Eight Analog Command Paths

  • Channel count: Eight output channels share the board interface while carrying separate analog commands.
  • Signal direction: Data moves from the controller and S100 I/O path toward field-side output circuits.
  • Board grouping: All eight outputs are organized on one DSAO 120A board.
  • Selection boundary: The channel count separates this board from four- and sixteen-output DSAO alternatives.

Rack-to-Field Data Flow

  • Rack interface: The board belongs to the S100 I/O family.
  • System support: Advant Master S100 I/O is supported through the documented System 800xA path.
  • Controller values: Output data reaches the board through the I/O architecture before being assigned to channels.
  • Field boundary: External analog circuits connect after the board has separated the controller values into eight outputs.

A-Version Output Supervision

  • Variant feature: OSP control is included on DSAO 120A.
  • Base-model distinction: DSAO 120 is listed as an eight-output board without the A-version OSP designation.
  • Configuration check: Engineering records must preserve the A suffix when OSP behavior is required.
  • Replacement check: Channel count alone is insufficient; the replacement identity must also include OSP control.

Ordering and Rack Match

  • Type designation: DSAO 120A identifies the ABB board type.
  • Ordering code: 3BSE018293R1 identifies the exact commercial configuration.
  • Architecture match: The receiving installation must provide the S100 I/O rack context.
  • Functional match: Eight analog outputs and OSP control must both agree with the installed board.
Description
ABB DSAO120A 3BSE018293R1 is an eight-channel analog output board in the S100 I/O family. It converts controller output values into eight separate analog field channels and includes the documented OSP control function on the A-version.

Within an S100 rack, ABB DSAO120A 3BSE018293R1 receives output data through the I/O architecture and distributes those values across its eight channels. Each channel therefore belongs to one common board interface while carrying an independent analog command to its field connection.

System 800xA can retain ABB DSAO120A 3BSE018293R1 as supported Advant Master S100 I/O through the documented integration path. Selection must match both the eight-output channel count and the A-version OSP function rather than treating DSAO 120 and DSAO 120A as identical boards.

Technical notes
ABB DSAO120A 3BSE018293R1 is the eight-output S100 I/O board variant that includes OSP control.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why must ABB DSAO120A 3BSE018293R1 be matched by both name and order code?
The full identity ABB DSAO120A 3BSE018293R1 combines the DSAO 120A board type with its exact ABB ordering code; the type alone is incomplete.
How many field commands can ABB DSAO120A 3BSE018293R1 issue?
Eight independent analog output channels on ABB DSAO120A 3BSE018293R1 carry eight separate controller output values.
What distinguishes ABB DSAO120A 3BSE018293R1 from DSAO 120?
Unlike the base DSAO 120 entry, ABB DSAO120A 3BSE018293R1 identifies the A-version with OSP control.
Where does ABB DSAO120A 3BSE018293R1 fit in the control architecture?
Within the control architecture, ABB DSAO120A 3BSE018293R1 occupies the S100 I/O layer between controller data and eight analog field circuits.
What must be checked before replacing ABB DSAO120A 3BSE018293R1?
A replacement for ABB DSAO120A 3BSE018293R1 must match the S100 rack interface, eight-output organization, A-version OSP function, and ordering identity.
