About the 0-52840-91

The 0-52840-91 is one of several Reliance Electric CCC cards available through AX Control for use within MaxPak Spindle drives.  These plug-in cards are no longer available through the original equipment manufacturer. 

The 0-52840-91 is a rectangular shaped board with a backplane connector and a narrow attached front faceplate.  The faceplate includes two screw pins to secure the unit within the chassis so it is secure within the rack system.   It also includes multiple dials on its front surface, the lowest one on a +/- scale, and the rest on a zero to ten scale.  Each dial connects on its backside to a potentiometer located on the front edge of the circuit board. 

The circuit board itself is sparsely populated, primarily with vertical pins to connect other components.  The board used surface wiring, capacitors, resistors, and diodes, but does not have any sort of tp test points or LED indicators.   Some components carry reference designators but most will be identified using the grid system printed on the board surface. 

The 0-52840-91 CCC card is one of six cards forming the basic drive regulator.   There are four terminal blocks that allow users to access the regulator, with 1TB and 2TB used for 120 VAC wiring.  Low-level signal wiring is placed on 3TB  or 4TB. The MaxPak Plus is designed for use in manufacturing settings that require a variable speed drive.
