Introduction to ABB DSAO130A 57120001-FG Analog Output Module
ABB DSAO300A 57120001-FG is a 16 channel analog output module in the ABB ADVANT-OCS (S800 I/O) DCS control system. It is used to convert controller operation results into continuous analog signals that can drive field actuators. It is the analog output layer interface between the control system and field devices such as regulating valves, frequency converters, and recorders.
core positioning
This module is designed specifically for process control scenarios that require multi-channel, high-precision analog signal output. It is one of the analog output modules with the highest channel density in the S800 I/O series and is widely used in DCS control circuits in industries such as power, petrochemicals, metallurgy, and water treatment.

Main functional features
Multi signal type support: Each channel supports current (4-20mA) or voltage (0-10V) output, which can be parameterized and configured through the bus to flexibly match different on-site device requirements.
High precision and linearity: 16 bit resolution, good output linearity, suitable for control circuits with high requirements for adjustment accuracy, such as flow regulation, temperature control, pressure control, etc.
Circuit monitoring: supports detection of signal abnormalities such as open circuits and short circuits, and fault information can be read through the Modulus Bus for quick identification of the fault channel.
Multiple protection: Built in overload protection, short circuit protection, and over temperature protection. In case of a fault, the output will be automatically cut off and the bus will be reported, reducing the risk of shutdown.
Channel status indication: Each channel is equipped with LED indicator lights, which can quickly determine the working status of the channel without the need for additional diagnostic tools.
Parameterized configuration: supports channel filtering time configuration through the bus (2/4/8/16ms four levels optional), effectively suppressing on-site high-frequency noise interference.
Hot swappable support: All S800 I/O modules support hot swappable replacement without cutting off the power supply to the I/O station system.
Start self check: Automatically check the electrical ID of the module when powered on, and do not enter the running state when it does not match the configuration, to prevent control abnormalities caused by mismatches.
Comparison with analog output modules of the same series
DSAO110 (57120001-AT) is an 8-channel analog output with fewer channels, suitable for small-scale signal output requirements. DSAO120 (57120001-EY) is an 8-channel analog output. DSAO300A is a 16 channel analog output module with the highest channel density in the S800 series, suitable for large-scale analog control circuits, such as multi-channel water supply regulation in power plants and multi-point temperature control in chemical industries.
Typical application scenarios
Power industry: generator set feedwater regulation, temperature and pressure reduction control, air door opening adjustment.
Chemical industry: reactor temperature regulation, feed flow control, pH value regulation output.
Metallurgical industry: simulation output for blast furnace air temperature regulation and rolling mill thickness control.
Water treatment: dosing control, effluent flow regulation, liquid level control output.
HVAC: control of chilled water valve opening and adjustment of air supply volume.
