About the 103779-33R
103779-33R
The 103779-33R is a Reliance Electric LTD circuit board component manufactured to be used within the company’s various drives. As there are several similar versions of this board available in the series, please confirm the version you need before placing your order. The 103779-33R is a Reliance board component, but your board may have originally shipped from Baldor-Reliance or from Asea Brown Boveri/ABB. Company structure changes account for the name changes.
The 103779-33R is a rectangular board with an extending tab from its rear edge. This tab is covered by a conductive material and acts as a sort of backplane for the board. The front edge of the board extends in three narrow tabs (right, left, and center) that each has been drilled through their center. These allow the board to be connected to the faceplate portion of the module. The faceplate is populated by two rotary dials connected to potentiometers.
The 103779-33R is a sparsely populated circuit board. It has nine rows of metal quick connect pins located on its surface. Most lines traverse the full or half the width of the circuit board. Some pins are labeled with numbers or other reference designators, but some are not labeled and do not connect to any sort of component. Other pins connect to metal film resistors or to surface wires. Surface wires on the board are typically black.
For more detailed information on the operation of the 103779-33R and for step-by-step installation instructions, please consult technical support publications originally provided to end users by Reliance Electric. This includes manuals, user guides, and data sheets.
