DSAX 108 57160001-ABD ABB Bailey

Product Dimensions：

The DSAX 108 57160001-ABD functions as a dual-purpose interface between the central processing unit of an Advant or MasterPiece controller and the field instrumentation. It converts continuous physical variables from the plant into digital signals for the controller, and conversely, translates digital control commands back into continuous electrical signals to drive final control elements. The module features integrated analog-to-digital (A/D) converters for its inputs and digital-to-analog (D/A) converters for its outputs. It communicationally interfaces with the controller via the specialized system backplane bus, ensuring deterministic data refresh rates necessary for closed-loop control.

Product Parameters

• Product ID: 57160001-ABD

• ABB Type Designation: DSAX 108

• System Compatibility: MasterPiece 200 / Advant Controller 410, 450

• Input Channels: 8 differential analog inputs

• Output Channels: 8 analog outputs

• Signal Ranges: Configurable for standard industrial ranges, typically $0-20 \text{ mA}$, $4-20 \text{ mA}$, or $0-10 \text{ V}$

• Resolution: 12-bit resolution for both input and output conversions, providing sufficient granularity for standard process control

• Galvanic Isolation: Features optocoupler isolation between the field-side electronics and the internal system logic bus to prevent ground loops

• Power Requirements: Draws power directly from the system backplane (typically $+5 \text{ VDC}$ and $\pm15 \text{ VDC}$ rails)

• Form Factor: Standard circuit board module designed to slide into dedicated I/O subracks

Product Advantages

A major advantage of the DSAX 108 57160001-ABD is its Space-Saving Combination Design. By housing 8 inputs and 8 outputs on a single board, it reduces the number of module slots required in the I/O rack, which lowers overall hardware costs and footprint. The High Galvanic Isolation protects the sensitive backplane microprocessor electronics from high-voltage transients or faults occurring in the field.

Additionally, the module provides High Reliability common to ABB's legacy industrial lines, built with heavy-duty components designed for decades of uninterrupted service. The hardware configuration is fully integrated into ABB’s control software (such as AMPL), allowing for Streamlined Configuration and direct mapping of I/O channels to control loop function blocks.

Important Considerations and Precautions

When maintaining or installing the DSAX 108 57160001-ABD, you must practice Electrostatic Discharge (ESD) Protection. This is an open-board module with exposed complementary metal-oxide-semiconductor (CMOS) components that can be permanently damaged by static electricity; always wear a grounded wrist strap when handling it. System Power Disconnection is highly recommended prior to inserting or removing the module from the subrack, as hot-swapping legacy MasterPiece boards can cause data bus disruption or hardware damage if not explicitly supported by the specific subrack revision.

Carefully check the DIP Switch Settings or jumper configurations on the board before installation; these physical hardware settings dictate the signal types (current vs. voltage) for the channels, and a mismatch with field wiring can result in false readings or component overheating. Lastly, because this is a Legacy/Discontinued Product, sourcing verified spares can be challenging, and plants should establish an inventory strategy or look into migration paths toward modern ABB Ability System 800xA I/O platforms.

Product Applications

The DSAX 108 57160001-ABD is utilized in vintage but operational process industries where MasterPiece and Advant systems control critical infrastructure.

• Pulp and Paper Mills: Regulating basis weight and moisture control loops by interfacing with scanning sensors and steam valves.

• Chemical Plants: Managing continuous temperature and pressure loops in legacy chemical reactor systems.

• Power Generation: Monitoring auxiliary analog parameters such as bearing temperatures and managing oil pressure control valves in older turbine setups.

• Water Treatment Facilities: Controlling chemical dosing pumps based on analog feedback from pH and turbidity meters.

• Metal and Mining: Interfacing with hydraulic positioning systems and furnace temperature sensors in metallurgical processes.
