About the 0-51901-A

0-51901-A Armature Regulator Drive Board

The 0-51901-A is a PCB board component manufactured by Reliance Electric for use within the company’s various drive systems.  

The  0-51901-A is designed to function as an Armature Regulator Drive Card. This circuit board has its backplane connector located along its long edge instead of on its short edge, like most boards in this board series.   The backplane is designed from an extending tail that has multiple conductive surfaces placed upon it. With this acting as the back edge of the board, the opposite ‘front’ edge has four potentiometers placed in a metal frame next to two relays.  The relays are placed sideways on the board facing toward the front edge. They wire into the circuit board using multiple surface wired connections. The potentiometers are labeled 1P, 2P, 3P, and 4P.

Other components located on the  0-51901-A includes four integrated circuits, transistors, disk capacitors made from ceramic material, polyester vinyl capacitors of various size, aluminum electrolytic capacitors, diodes, and resistors.  Most resistors are made from metal film. Some capacitors are large enough to need secondary support; this is typically given by zip ties threaded through the board’s surface.

The  0-51901-A is marked on its rear edge with the codes 4797 and 82746-74C.  It is imprinted with the Reliance logo. More information about installation, operation, and maintenance of this component may be found through technical support publications originally provided by the manufacturer, such as user guides and manuals.  Reliance Electric provided all support for this product. Please follow all handling and safety procedures as recommended by the manufacturer.

Internal Review
(5.0)

This 0-51901-A Reliance Electric printed circuit board product offering is functionally defined in the now-defunct retailer's sparsely-available instructional documentation as a Armature Regulator Drive Board, although it is an edited version of the original product with this functionality. Several zip ties are included in its assembly for the reinforcement of various 0-51901-A voltage-limiting hardware components. - AX Control Lead Technician
