0-52840-488 Modified PC Board
The 0-52840-488 is a Reliance Electric circuit board fabricated for use within various drives from the company. While this circuit board is usually manufactured by Reliance, it can sometimes originate from Asea Brown Boveri or Baldor-Reliance. The 52840-488 designator will appear in the part ID. This board component has been discontinued.
The 0-52840-488 is a modified PC board. The rectangular circuit board is marked with a grid pattern and has a short extruding tail on its rear edge that acts as a conductive backplane. The board is primarily empty except for brass vertical pin connectors. Some of these connectors are labeled with designators or appear in boxes with designations. Other components on the board’s surface include capacitors made from various materials, including ceramic and polyester vinyl, resistors, and surface wires. The board also includes eight potentiometers.
The 0-52840-488 has a front faceplate. The faceplate has a set screw located on the top and bottom edge that allows technicians to lock the module into place once it is inserted into a rack system. There are eight rotary dials in the faceplate. These each connect to one of the potentiometers on the surface of the circuit board. Each dial is individually labeled.
Detailed information about the 0-52840-488 can be found through product manuals, user guides, and data sheets originally provided by Reliance Electric for ongoing technical support. The same publications will have information about installation, maintenance, and proper handling of the component. Please read and follow all safety procedures before beginning any type of work on the 0-52840-488 or its individual components.
