      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • ABB DSAO120 57120001-EY converts controller output values into analog signals for process equipment. Channel wiring selects the voltage or current output function in the matched DSTA170 arrangement.
      Product type: Eight-channel analog-output board
      Signal ranges: 0 to ±10 V or 0 to ±20 mA
      Resolution: 12 bits including sign; non-isolated outputs
      DSAO120 provides eight analog-output channels for an Advant S100 I/O system. Its nominal signal ranges are 0 to ±10 V or 0 to ±20 mA, with 12-bit resolution including sign. These bipolar outputs allow the controller to command an appropriately matched field device through either a voltage or current interface.

      The channels are not galvanically isolated. Current or voltage operation is selected by connecting the signal wiring to the corresponding terminals on DSTA170, rather than by treating the voltage and current connections as independent channels. The complete installation includes the output board, appropriate connection cable and field connection unit.

      Front-mounted potentiometers provide gain and zero-point adjustment. The analog-output boards are factory adjusted for current output; using voltage output may require readjustment to obtain the applicable accuracy. Preserve the installed channel scaling and use the ABB adjustment procedure and suitable test equipment before returning a changed channel to control service.
      Controller platform reference: ABB Advant S100 I/O. Match the controller and configured I/O arrangement.
      Technical downloads for DSAO120 57120001-EY: an original ABB reference excerpt and an Apter Power installation planning guide.
      The DSAO120 functions apply to DSAO120 57120001-EY with its matched S100 connection unit. DSAO120A isolation and OSP features are separate and are not assigned to this board. The planning guide is prepared by Apter Power; apply the complete manufacturer instructions and the stated applicability boundaries.
      System and supply context: The DSAO120 functions apply to DSAO120 57120001-EY with its matched S100 connection unit. DSAO120A isolation and OSP features are separate and are not assigned to this board. Accessories are included only when itemized in the quotation.

      Platform applications: The following applications describe Advant S100 I/O functions. Match the complete DSAO120 57120001-EY identity to the installed system before selecting a replacement.
      Prepare DSAO120 57120001-EY against the installed configuration and applicable ABB instructions. Plan isolation and the resulting interruption of system operation before replacement.
      Preserve the exact variant

      Retain DSAO120 57120001-EY; DSAO120A has different isolation and configuration characteristics.

      Review signal connections

      Check whether every field circuit uses voltage or current and record its return path.

      Observe non-isolated wiring

      Assess grounding and connected circuit potentials for the non-isolated DSAO120 outputs.

      Control the process before work

      Prevent unintended equipment movement or process changes before disconnecting outputs or adjusting a channel.

      Use a controlled adjustment

      Preserve the original settings and use suitable measurement equipment and the applicable ABB procedure.

      Test every affected channel

      Confirm the commanded and measured signal, polarity, scaling and field response before restoring automatic operation.

      FAQ View All FAQ

      • How many output channels does DSAO120 57120001-EY provide?
        DSAO120 provides eight analog-output channels. Voltage and current terminals are connection choices for those channels, not separate additional outputs.
      • What nominal signal ranges apply to DSAO120 57120001-EY?
        The DSAO120 design provides 0 to ±10 V or 0 to ±20 mA. Match the field load and controller scaling to the selected signal type.
      • What conversion resolution does DSAO120 57120001-EY use?
        The specified resolution is 12 bits including the sign. Do not substitute the 12 bits plus sign description of DSAO120A.
      • Are the outputs of DSAO120 57120001-EY galvanically isolated?
        No. DSAO120 has non-isolated outputs. DSAO120A is a separate design with different isolation characteristics.
      • How is the signal type selected for DSAO120 57120001-EY?
        Current or voltage is chosen through the signal connection on the matched connection unit. DSTA170 provides the appropriate field-wiring connections.
      • Which adjustments are accessible on DSAO120 57120001-EY?
        Gain and zero-point adjustments are provided by potentiometers on the front. Adjustment should follow the applicable ABB procedure and the installed channel configuration.
      • Is DSAO120 57120001-EY factory adjusted for voltage output?
        The analog-output boards are factory adjusted for current output. Voltage operation may require readjustment to achieve the applicable accuracy.
      • What must be checked before changing a channel on DSAO120 57120001-EY?
        Check voltage/current selection, return wiring, scaling and the effect on the controlled load. Secure the process before adjustment and verify the restored output under controlled conditions.
