About the 0-56951-301AA
0-56951-301AA Regulator Board
The 0-56951-301AA is a Reliance Electric circuit board manufactured for use in the company’s drives.
The 0-56951-301AA is designed as a Regulator Board with a four-digit display under a touchpad display/keypad. The keypad component fits over the circuit board as a metal carrier, and connects to the board via four screw mounts through factory made drill holes on the board’s surface. The keypad/display leaves the upper quarter of the board exposed. This part of the board is populated by a sixteen-position terminal strip, a relay, and several integrated circuits. Below these is the four-digit display, placed over two lines of four red LED indicators. The display and the LEDs correspond to openings in the overlying panel. The LEDs are labeled RPM, % Load, Volts, Remote, Run, Program, Forward, and Reverse. The front panel also includes an up and down toggle switch, a stop/reset button, a start button, a mode/enter button, and a forward/reverse button.
Other parts on the 0-56951-301AA circuit board include two right-angled cable connectors, transistors, resistors, a processing chip along with other integrated circuits, and capacitors. The cable connectors allow data to transfer from the board to the panel and to other board components.
For more information regarding installation or operation of the 0-56951-301AA, consult publications from Reliance such as user guides or manuals. These technical support publications should have arrived with your OEM purchase. If you no longer have these publications on-hand, please let your AX Control sales representative know when placing your order for your replacement part, as we may be able to source replacements.
