Information About 103779-2R

The 103779-2R is a control board manufactured by Reliance Electric LTD. for use across multiple drive platforms produced by the company. Due to corporate transitions, the same board may be found branded under Baldor-Reliance or ASEA Brown Boveri, though the part number remains consistent. The board integrates a mechanical faceplate with electrical control circuitry, allowing direct operator adjustment of key drive parameters through wired potentiometers. It is commonly installed in industrial drive systems where manual tuning and local control inputs are required.

Key Features

• Integrated Adjustment Faceplate: Combines the control interface and circuit board into a single assembly for direct operator access.
• Four Precision Rotary Dials: Provides adjustable inputs for Limit 1, Limit 2, Zero Speed Adjustment, and Jog control.
• Fine Increment Control: Each dial adjusts from 0 to 10 in 0.2 increments for accurate parameter tuning.
• Potentiometer-Based Inputs: Rotary dials connect to rear-mounted potentiometers wired directly into the PCB.
• Extensive Connection Points: Features eight rows of vertical quick-connect pins for flexible system integration.
• Conductive Backplane Design: Rear edge extends into a conductive backplane to support electrical continuity.
• Legacy Drive Compatibility: Designed for use in multiple Reliance Electric drive systems across different branding eras.

The 103779-2R delivers the reliability and precision required for manual parameter adjustment and control input in Reliance Electric industrial drive systems.
