+86 153 5940 8275Analog Output Module · S100 I/O
ABB DSAO120 is an eight-channel analog output board for the ABB S100 I/O family. Order 57120001-EY identifies DSAO120; the ABB catalog lists bipolar voltage and current ranges of ±10 V and ±20 mA and resolution of 12 bits including sign.
Match each output to the receiving instrument and the installed terminal arrangement. The ABB catalog gives a net weight of 0.46 kg and identifies front plate 29491274-12. DSAO120 and DSAO120A are separate entries in the ABB hardware guide; the latter is explicitly described with OSP control.
Before replacement, preserve channel assignments, engineering-unit scaling and output polarity. Exercise outputs using an approved test arrangement that prevents unintended actuator movement, then confirm the receiving device indication. Retain the complete order number and board revision in the commissioning and purchasing records.

Record all eight output assignments and their voltage or current modes. Control connected actuators during testing and preserve the installed scaling.
For 57120001-EY, the ABB catalog wording is 12 bits including sign. Keep that exact distinction; specifications quoted for DSAO120A must not silently replace the DSAO120 catalog value.
ABB lists ±10 V and ±20 mA. Check the installed channel setup and receiving instrument before applying either signal type; a current input and a voltage input require different test arrangements.
Record the terminal destination, signal mode, polarity and engineering-unit range for each channel. This creates a channel-by-channel comparison for the replacement commissioning test.
No. ABB lists DSAO120 as an eight-output board and separately lists DSAO120A with OSP control. Determine the installed output behavior from the correct model documentation and controller configuration.
A correct controller command does not by itself prove the field signal or actuator response. Compare the commanded value with a suitable measurement and the receiver indication under a controlled test procedure.
ABB references this front plate in the DSAO120 technical information. It is a mechanical identification reference and should be checked separately from the board order number 57120001-EY.
Bipolar outputs can command a response on either side of zero. Confirm polarity, permitted actuator movement and the approved test range before exercising negative voltage or current values.
Specify DSAO120, 57120001-EY and eight-channel analog output functionality. The direction of the signal is essential: an analog-input board cannot replace an output board simply because both belong to S100 I/O.
Send the model, complete part number, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
