About the 0-52711-8
0-52711-8 Frequency Input Card
The 0-52711-8 is a Frequency Input Card fabricated by Reliance Electric. There are two circuit boards in this component, connected together by screw connections and standoffs. These boards are usually marked with the Reliance Electric logo, but may also originate from ABB or from Baldor Reliance.
The 0-52711-8 functions as a Frequency Input Card. The lower board includes multiple integrated circuits, transistors, a rectifier diode, surface wiring, metal film resistors, and ceramic capacitors. The board has several vertical pin components to allow for the connection of surface wires. The front edge of the board has an oval cut-out. Both the front and back edge of the board is populated by large black components that are screw mounted to the surface of the board. The component closest to the front edge is labeled “input” and includes several screw mounts.
The top board of the 0-52711-8 is similar to the bottom board. It has an input component with screw mounts located along its front edge, and it also has several vertical pins to connect to surface wiring. The top board has thirteen integrated circuits, two transistors, several metal film resistors, a capacitor, and several diodes. Both boards are printed in a grid pattern.
More information regarding the operation of this component may be found through Reliance publications. Please follow all manufacturer recommended safety procedures.
