ABB DSPB 120 57340001-T MasterView 800 Display Processor

Product Overview

The ABB DSPB 120 (57340001-T) is a dedicated display processor module developed for the MasterView 800 operator interface sub-system. It operates within the legacy ABB Advant Master Process Control System architecture. This module provides the central processing capabilities required to drive operator station displays, manage real-time graphical rendering, and process operator input commands from the control room console. The unit functions as a central unit accessory within the control system hierarchy, facilitating interface communication between the process controllers and the visual display monitors. The DSPB 120 is exempt from the scope of the 2011/65/EU (RoHS) directive under Article 2(4)(c), (e), (f), and (j) provisions for heavy industrial installations and large-scale fixed tools, as documented in the official EU Declaration of Conformity (3BSE088609) for the Advant Master system.

Engineering & Installation Guide

Grounding and Shielding Requirements

To prevent graphical noise and communication dropouts on the MasterView 800 console, the DSPB 120 must be securely bonded to the functional earth rail of the equipment rack. Ensure the sub-rack chassis ground has a low-impedance path to the primary master station earth. Shielded cables used for console monitors or keyboard connections must be grounded at both ends using standard EMC grounding clamps before entering the module casing.

Cabinet Ventilation and Thermal Management

The module relies on convection cooling within the sub-rack housing. Maintain a minimum clearance of 50 mm above and below the card cage assembly to prevent localized heat buildup. If the cabinet's internal temperature regularly exceeds 40°C, forced ventilation using filter fans must be installed at the bottom of the enclosure to ensure consistent airflow across the processing board components.

Obsolescence and Lifecycle Management

The DSPB 120 is part of a legacy system architecture. Maintenance supervisors should maintain a strategic warehouse stock of tested, original replacement modules to mitigate downtime risks during unexpected component wear. When swapping hardware, always power down the sub-rack assembly to protect the backplane pins from electrical arcing during module insertion or extraction.

Frequently Asked Questions

What is the significance of the RoHS exemption note for this module?

The DSPB 120 is explicitly exempt from the scope of the 2011/65/EU (RoHS) directive as specified under Article 2(4). This exemption applies because the module is designed specifically as a spare part for large-scale fixed industrial infrastructure installations, particularly the ABB Advant Master Process Control System, which itself falls outside the scope of the standard RoHS directive.

Can the DSPB 120 be hot-swapped while the sub-rack is energized?

No. Live insertion or removal of the DSPB 120 display processor can cause transient voltage spikes across the system backplane, potentially corrupting the display bus or damaging adjacent central units. Always isolate the sub-rack power supply before performing hardware replacements.

Which system families are compatible with this processor?

This display processor is designed for the MasterView 800 operator stations running under Master SW control software within the Advant OCS network architecture. It cannot be used in modern System 800xA panels or alternative Freelance architectures.
