About the 0-52803-2

0-52803-2 FVCC Frequency to Voltage Converter Board

The 0-52803-2 is a Reliance circuit board component that has been manufactured for the company’s drive systems.  This is a circuit board and faceplate module that usually is marked with the Reliance logo; in some cases, however, it may carry ABB or Baldor Reliance markings instead.  This can be attributed to changes in company structure. The 52803-2 number should remain as the part number in all cases.

The 0-52803-2 is a Frequency to Voltage Converter Card.  The circuit board connects to a faceplate with a ten-screw terminal strip and a single opening for a potentiometer.  This opening is labeled “gain.” The connections on the terminal strip wire into the surface of the board using surface wiring from their back edge to the board’s surface.  

Other components used on the surface of the 0-52803-2 include two additional potentiometers, transistors, surface wiring, metal film resistors, and carbon composite resistors along with diodes.  The board has capacitors made from several kinds of materials. This includes ceramic disk capacitors. The board has thirteen integrated circuits. Circuits are marked on their top surface with manufacturer part numbers.  The board has a conductive backplane connector extending from its rear edge. TP test points are located in several places on the board’s surface. The board is marked across its surface with a grid pattern. It is drilled in multiple locations.  

Reliance product manuals and user guides will provide the end user with more detailed information regarding the operation of the 0-52803-2.  These publications will also provide more information regarding proper installation procedures.
