About the 0-51378-44
The 0-51378-44 is a Gate Coupler board from Reliance Electric. It is typically used in conjunction with one of several Reliance thyristor assemblies and is attached to the top surface of this product. Gate coupler boards from Reliance may be marked as coming from Baldor Reliance or Asea Brown Boveri (ABB) depending on the year of production. The board number/part number should remain the same regardless of the company name or logo stamped on the product.
The 0-51378-44 is a small board. It has only a few components located on its rectangular surface. Among these includes pin connectors labeled H1 and H2, a stab-on connector, a resistor, two capacitors, and two diodes. At the center of the board, there is also a single transformer mounted in a frame. The board is marked with the Reliance logo and with the board identification number. It also has been drilled at either long end with a factory-made hole that has been reinforced on the bottom side for ease of mounting.
