ABB DSAX 108 57160001-ABD 8-Channel Relay Connection Unit

Description

ABB DSAX 108 57160001-ABD 8-Channel Relay Connection Unit

The ABB DSAX 108 (Part Number: 57160001-ABD) is a legacy, highly specialized sub-module component utilized within the ABB Advant OCS (Open Control System) with Master software or MasterPiece series controllers. It functions primarily as an Analog Input/Output or specialized functional expansion board within that Distributed Control System (DCS) ecosystem.

Product Detailed Description

The DSAX 108 card acts as an interface between the central processing units of the Advant OCS system and the industrial field instruments. As a component of the MasterPiece/Advant Master architecture, it is designed to capture highly precise analog measurements from field transmitters or output precise control signals to final control elements (such as valves or actuators). The specific suffix 57160001-ABD represents the exact hardware manufacturing part number, designating the revision and component assembly build for standard industrial use.

Technical Parameters

Product Advantages

• Proven DCS Reliability: Engineered to live-up to the rigid requirements of continuous process industries, offering a very high Mean Time Between Failures (MTBF).
• High Signal Integrity: Features advanced built-in noise filtration and galvanic isolation to protect the delicate system CPU from field-side voltage spikes or ground loops.
• Seamless Backplane Integration: Communicates natively across the proprietary ABB MasterPiece backplane without requiring complex protocol mapping.
• Deterministic Performance: Processes analog variables at fixed, high-speed intervals, satisfying the needs of critical control loops.

Important Considerations & Precautions

• Electrostatic Discharge (ESD): This is an open-frame circuit board module. Always wear a grounded ESD wrist strap when handling or moving the module to avoid ruining the onboard CMOS ICs.
• Legacy Compatibility: Ensure your MasterPiece backplane and current software revision fully support the firmware version hardcoded onto the DSAX 108 board.
• Slot Alignment: Turn off sub-rack power (unless hot-swapping is explicitly permitted by your specific rack type) before seating the board. Ensure the pins line up cleanly with the backplane connector to avoid physical damage.
• Recalibration: Since it is a legacy analog board, check the channel drift or zero/span settings during routine maintenance turnaround periods.

Product Applications

The DSAX 108 module is typically used in existing, long-standing industrial automation loops:

• Petrochemical & Refining: Monitoring temperature, flow, and level sensors in heavy processing sectors.
• Power Generation: Regulating water chemistry loops or turbine parameter telemetry inside power plants.
• Pulp & Paper Systems: Managing wet-end analog signals and motor speeds across legacy production machinery lines.
• Steel & Metallurgy: Interfacing with high-capacity heating controllers and cooling instrumentation loops.
