About the 0-58770-220BC

0-58770-220BC PC Regulator Assembly Board

The 0-58770-220BC is a circuit board component fabricated by Reliance Electric to be used in their drive assemblies, most often the FlexPak 3000.  This board has been discontinued and is no longer manufactured. 

The 0-58770-220BC functions as a Drive board for the Regulator assembly.  The board is factory drilled to allow mounting hardware to be installed.  The edges are marked in half-inch increments.   It has multiple connectors,  including a long terminal strip along one edge, two vertical pin cable connectors along a second edge, and a third vertical pin cable connector on the opposite edge.  These connectors have stabilizing clips located at each end.   The board also has a right-angled cable connector next to the terminal strip, as well as several connectors located within the body of the board. 

Other board components located on the surface of the 0-58770-220BC include four relays, stab-on connectors, jumper switches, transistors, and multiple integrated circuits, including oscillating chips and memory ICs. Each relay has a printed relay diagram on its top surface.  The board has two LED indicators built into the interior body, facing upward.  It also uses resistors, capacitors, Zener diodes, and other diodes.  Capacitors vary in type and medium. 

For more detailed information regarding board operation, or for installation instructions along with a troubleshooting guide, please consult publications from Reliance like product data sheets and manuals.  The FlexPak 3000 user guides may also be helpful.  Technical support publications may be published under the names of Reliance Electric, Baldor-Reliance, or ABB.
