Description

Product Overview

The DSPC172 57310001 is an ABB Advant Master processor unit used as a central processing component in legacy ABB Master control systems. ABB product documentation identifies DSPC172 as a processor unit and lists the corresponding product family under the Advant Master Process Control System. ABB also distinguishes related versions such as the DSPC172H, so the complete ordering suffix should be verified carefully before procurement.

This type of processor is responsible for executing control-system processing and coordinating functions within the controller architecture. For maintenance teams supporting long-running DCS installations, retaining an appropriate processor spare can be important where an unexpected CPU failure could affect system availability. The exact hardware designation, revision, and associated memory configuration should be checked against the installed controller before replacement.

Technical Specifications — DSPC172

ABB’s published product listing identifies DSPC172 as a processor unit, while separate documentation identifies the DSPC172H as a different processor-unit designation with product ID 57310001-MP. These should not be assumed interchangeable solely from the similar model names.

Key Features and Benefits — DSPC172

• Designed for ABB Advant Master control-system applications.
• Provides central processing functions within the DCS controller architecture.
• Suitable for maintenance, lifecycle support, and critical-spares inventory.
• Rack-mounted architecture supports integration with established ABB control-system hardware.
• Useful for sustaining legacy automation installations where complete system migration is not practical.
• Full ordering-code verification helps prevent substitution with a different DSPC revision.
• Appropriate for controlled MRO inventory with documented hardware traceability.

The processor family is associated with ABB’s Advant Master product line, which means procurement teams should focus on system compatibility rather than relying on a generic description such as “ABB CPU board.” ABB’s own spare-parts documentation lists DSPC172 under Advant Master.

Related Models

DSPC172H — A related ABB processor unit identified by product ID 57310001-MP. The H version should be treated as a distinct ordering configuration.

DSPC171 — Earlier DSPC processor-family hardware associated with ABB Master control systems.

DSPC170 — Processor-family variant used within the Advant Master generation.

DSMB179 — ABB memory module used within the Advant Master spare-parts architecture and listed alongside processor hardware in ABB documentation.

Installation and Maintenance — DSPC172

Before replacement, confirm the complete ordering code, installed revision, rack position, controller architecture, and associated memory hardware. Record the existing configuration and communication connections before removing the processor.

Use ESD precautions when handling the board. Inspect the replacement for connector damage, corrosion, contamination, and physical impact. After installation, verify controller startup, diagnostics, communication status, and configured process functions before returning the system to production.

Personally, I would compare the original nameplate and hardware revision against the replacement before installation. On older Advant Master systems, similar DSPC designations can represent different hardware configurations, and that distinction matters during an emergency swap.

Product Warranty — DSPC172

Warranty conditions depend on the supplier and supplied condition. Confirm whether the unit is new, unused surplus, refurbished, or previously installed, and request available inspection or functional-test documentation.

For critical Advant Master inventory, retain the complete ordering number, hardware revision, serial number where applicable, inspection status, and storage history. This provides traceability and helps prevent an incorrect processor from being issued during an urgent DCS maintenance event.
