About the 51425-1
The 51425-1 module is a rectifier AC tach circuit board that was designed and produced by Reliance Electric. AX Control continues to stock the 51425-1 circuit board despite it being no longer available new from or supported by the original manufacturer.

The 51425-1 circuit board is small, but it has quite a few electrical parts placed throughout its surface. The most noticeable part on the board is the large potentiometer toward the bottom left corner. Above this potentiometer, there is whtie text which reads “MAX SPD.” There is also a large resistor that covers almost the entire length of the board. This particular resistor is the 63481-XLB model, which has 10 Watts of power and 10,000 Ohms of electrical resistance. Below this large resistor, you will see five pieces of much smaller electrical components. In addition to all of those, there are five screws that are secured by metal frames. There are, however, two screws that are not, and these screws are much longer and are meant to attach the 51425-1 circuit board to the rest of the system that it is being installed into.
The 51425-1 circuit board is very light in weight at only approximately 0.17 lbs. or 0.077 kg. This total does not include any of our packaging materials.
