Allen-Bradley 80190-380-02-R SCB Rectifier Board

Overview

The 80190-380-02-R is a legacy Allen-Bradley rectifier and signal conditioning board developed for Rockwell Automation medium-voltage drive platforms. This assembly belongs to the 80190-380 control-board family used in PowerFlex MV systems and auxiliary drive-control subsystems.

Designed as an internal MV-drive component, the board performs regulated AC-to-DC conversion while supplying conditioned feedback signals to the main drive controller. The “-02-R” hardware revision incorporates an updated circuit layout together with conformal coating protection for improved durability in contaminated industrial environments.

This module is commonly found in PowerFlex 7000 drive cabinets, retrofit projects, and long-term maintenance inventories for existing Rockwell installations.

Main Functional Characteristics

• Converts 120/240 VAC input into regulated low-level DC output

• Supports stable voltage reference and feedback processing

• Conformal-coated PCB improves resistance to moisture and airborne contaminants

• Intended for medium-voltage drive control architectures

• Compact board structure suitable for replacement maintenance

• Supports continuous-duty industrial operation

• Integrated into MV-drive power supply and control sections

Technical Specifications

Typical Applications

The 80190-380-02-R board is typically installed in:

• PowerFlex 7000 medium-voltage drives

• Rockwell Automation MV control cabinets

• Industrial drive retrofits

• Legacy motor-control systems

• Process automation equipment

• Manufacturing and utility drive systems

Environmental Protection Features

The conformal-coated surface applied to the 80190-380-02-R helps protect the circuitry from:

• Conductive dust accumulation

• High-humidity environments

• Chemical vapor exposure

• Corrosion caused by industrial contaminants

This makes the board suitable for operation in heavy industrial sectors including mining, petrochemical processing, energy production, and continuous-process manufacturing facilities.

Compatibility Information

The 80190-380-02-R belongs to the same functional product family as the 80190-380-01-R series. While both modules share similar operating characteristics, the “02-R” revision includes updated board architecture and revised coating protection for enhanced field reliability.

FAQ

Is the 80190-380-02-R still manufactured by Rockwell Automation?

No. This module is considered a discontinued legacy MV-drive component with limited market availability.

What is the main function of this board?

Its primary role is AC-to-DC rectification combined with low-level signal conditioning and voltage feedback support for medium-voltage drive systems.

What does the “-R” suffix represent?

The suffix identifies a conformal-coated version designed for improved environmental protection and longer service life in industrial applications.

Can this board replace the 80190-380-01-R version?

In some MV-drive systems the modules may be functionally related, but compatibility should always be verified using the drive assembly documentation and hardware revision requirements.
