103779-2R | Reliance Electric CC1 Module PLC Card Slot Rack Controller

The 103779-2R, manufactured by Reliance Electric LTD., is a versatile board component designed for integration with various drive systems within the company’s product range. Due to company restructuring, this part may also be branded as Baldor-Reliance or Asea Brown Boveri, reflecting its broad compatibility and utility across different product lines.

This rectangular circuit board is equipped with an attached faceplate, which provides a user-friendly interface for adjusting drive parameters. The faceplate features four rotary dials, labeled 'Limit 1,' 'Limit 2,' 'Zero Spd. Adjust,' and 'Jog.' These dials are essential for fine-tuning the operational settings of the drives, offering precise control over various performance parameters.

Each rotary dial on the faceplate is adjustable from zero to ten, with increments of two-tenths, allowing for fine-grained adjustments. These dials connect to potentiometers mounted on the rear surface of the faceplate, providing accurate and reliable control inputs. The potentiometers are wired to the quick-connect pins on the circuit board, ensuring seamless and efficient connectivity.

The circuit board itself is designed with three tabs on the front edge, securely connecting it to the faceplate and maintaining structural integrity. The rear edge of the board extends into a conductive backplane, which facilitates robust electrical connections and enhances the overall reliability of the component.

On the surface of the board, there are eight rows of vertical metal quick-connect pins. These pins are marked with designators, although some are left blank. These pins are integral to the board’s connectivity, providing multiple connection points for various components and wiring. Surface wires connect to some pins, while resistors span the gaps between others, ensuring proper electrical continuity and functionality.

The design of the 103779-2R prioritizes ease of integration and reliable performance. The faceplate potentiometers, wired directly to the quick-connect pins on the circuit board, offer straightforward and efficient setup. This design minimizes the complexity of installation and ensures that adjustments made via the faceplate are accurately transmitted to the drive system.

The 103779-2R's robust construction and thoughtful design make it an ideal component for use in industrial drive systems. Its ability to handle precise adjustments through the rotary dials and potentiometers ensures optimal performance and reliability in various applications. Whether branded under Reliance Electric LTD., Baldor-Reliance, or Asea Brown Boveri, the 103779-2R remains a critical component for enhancing the functionality and control of drive systems.

In summary, the 103779-2R board component by Reliance Electric LTD. is a meticulously designed, high-quality piece of hardware essential for optimizing drive performance. Its comprehensive features, including adjustable rotary dials, secure connectivity options, and robust construction, make it a versatile and reliable choice for a wide range of industrial applications. Whether used in new installations or as a replacement part, the 103779-2R provides the precision and dependability required for efficient drive system operation.
