Product Overview

The ABB 1MRK000167-ACr06 Printed Circuit Board is an industrial electronic circuit board associated with ABB’s 1MRK000167 processing hardware family. It is designed as an internal electronic assembly for compatible ABB protection and control equipment rather than as a standalone programmable controller.

Printed circuit boards are essential components in industrial automation and electrical protection systems. They provide the physical platform for electronic components, signal paths, connectors, and processing circuits. Within a larger control device, a PCB can support functions such as data processing, internal communication, signal handling, and coordination between electronic assemblies.

The 1MRK000167 product family includes processing-related hardware. The base designation 1MRK000167-AC is identified in product references as a Main Processing Module. The ACr06 suffix identifies a particular board version and should be retained when checking replacement compatibility. The exact hardware configuration and host-equipment assignment should be confirmed against the original ABB documentation and the installed system.

In industrial applications, a processing-related board forms part of the equipment’s internal electronic architecture. It works with other designated assemblies and depends on the host device for power, mounting, signal connections, and system-level operation.

The ABB 1MRK000167-ACr06 is relevant to maintenance and spare-parts procurement where an existing installation requires the same identified board version. Because circuit boards with similar base numbers may have different hardware revisions or functions, buyers and maintenance engineers should verify the complete part number before installation.

Technical Specifications

Note: The dimensions and weight are the supplied product-listing values. Detailed electrical ratings, connector assignments, firmware requirements, and environmental limits should be verified using documentation for the specific host equipment.

Function and Working Principle

The ABB 1MRK000167-ACr06 is an internal circuit board. Its operation depends on the electronic architecture of the ABB equipment in which it is installed.

1. Electronic Processing Architecture

Processing-related circuit boards provide the electronic hardware needed for designated internal control and processing tasks. Depending on the host system, this may involve handling data, coordinating internal operations, and exchanging information with other electronic assemblies.

The exact functions of the ACr06 revision should be confirmed against the corresponding equipment documentation. It should not be assumed that every board in the 1MRK000167 family has identical circuitry or functionality.

2. Internal Signal Handling

Industrial protection and control equipment receives information from measurement circuits, input interfaces, and other electronic components. Internal circuit boards provide the electrical paths and processing hardware required to handle this information.

A processing-related board may participate in transferring information between internal assemblies. The exact signals, interfaces, and communication protocols depend on the host equipment design.

3. Communication with Other Assemblies

A PCB installed inside an industrial device may connect to other boards through connectors, backplane interfaces, or dedicated wiring. These connections allow the equipment’s electronic assemblies to operate as a coordinated system.

Connector position and hardware revision are important. A board with a similar model number may have a different interface arrangement and may not be compatible with the same installation.

4. Host-System Dependency

The 1MRK000167-ACr06 is not a complete standalone controller. It requires the appropriate ABB host equipment, electrical connections, mounting arrangement, and system configuration.

Its operating conditions are therefore determined by the equipment in which it is installed. Power supply requirements, temperature limits, firmware compatibility, and commissioning procedures must be checked at the system level.

Role in Industrial Control and Protection Systems

Processing-related electronic boards contribute to the operation of industrial protection and control equipment. Their role is particularly important in installations where reliable electronic processing and coordination are required.

Protection Equipment

Electrical protection systems monitor operating conditions and respond to abnormal electrical events. Internal processing hardware supports the electronic operations required by the protection device.

The exact protection functions are determined by the complete relay or control equipment, its firmware, and its configured application. The 1MRK000167-ACr06 should be treated as an internal board rather than as a complete protection relay.

Substation Automation

Substation automation systems combine protection devices, measurement equipment, communication interfaces, and control systems. Internal processing boards form part of the electronic hardware used by compatible protection and control equipment.

In these installations, accurate hardware identification is important because an incompatible board can affect equipment startup, internal communication, or system operation.

Industrial Electrical Control

Industrial facilities use electrical protection and control equipment to monitor and manage power distribution. Processing-related PCBs support the internal electronic functions of designated devices used in these systems.

The board’s suitability depends on the exact ABB equipment model and the original hardware configuration.

Equipment Maintenance

A model-specific PCB can be used when servicing equipment that originally contains the same board version. Matching the complete part number helps reduce the risk of replacing a board with an incompatible revision.

Maintenance teams should also preserve configuration records and follow the manufacturer’s installation and commissioning instructions.

Industrial Applications

The ABB 1MRK000167-ACr06 is intended for use within compatible ABB protection and control equipment. Its application should be determined by the host device rather than by treating the PCB as an independent field instrument.

1. Electrical Protection Systems

Protection equipment uses electronic hardware to process measurements and support protection logic. A processing-related board may form part of the internal electronic architecture of compatible ABB equipment.

The complete protection device determines the available functions, measurement capabilities, and protection settings.

2. Substation Control Equipment

Substations contain protection and control devices that coordinate electrical system monitoring and operation. Internal processing boards support the electronic operation of designated equipment in these installations.

When maintaining substation equipment, engineers should verify the board revision and the corresponding device configuration before replacement.

3. Power Distribution Installations

Industrial power distribution systems rely on protection and control equipment to monitor electrical conditions and support safe operation. A compatible internal PCB can be part of the electronic hardware used by these devices.

The board must be installed only in the equipment for which it is specified.

4. Industrial Automation Infrastructure

Large industrial facilities may integrate electrical protection equipment with supervisory control and automation systems. Processing hardware inside the protection equipment supports its internal functions, while system-level integration depends on the host device’s interfaces.

The 1MRK000167-ACr06 should not be assumed to provide a direct PLC communication interface without confirmation from the equipment documentation.

5. Maintenance and Spare-Parts Replacement

Industrial installations may require replacement circuit boards when an existing assembly becomes damaged or fails diagnostic checks. A matching board can help restore the original equipment configuration.

Before ordering, confirm the full model designation, suffix, board markings, connector layout, and host-equipment model.
