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).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. 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.
