Product Description
845222-R Reliance Electric Board component
The 845222-R is a Reliance Electric board component used within Reliance drives and their auxiliary systems. This board component was distributed under various company names, including Asea Brown Boveri/ABB, Reliance Electric, and Baldor-Reliance.
The 845222-R is a rectangular board with auxiliary board attachments and an attached front faceplate. The faceplate component connects to the circuit board by screw connections. The front panel has seven rotary dials mounted into its surface. Each of these dials is individually labeled and numbered. Each dial connects to a potentiometer that is mounted on the rear of the front panel and connects to the circuit board. The front panel also has two set screws that are placed one at the top edge and one at the bottom edge; these are used to lock the module safely in place once it is installed into a rack.
The circuit board portion of the 845222-R is primarily populated by terminal pins. The board also has four large polyester vinyl capacitors placed side-by-side, along with a few other components like resistors and diodes. A vertical metal framework takes up the back edge of the board; this protects and holds the auxiliary board. This board has additional components on its surface, including transistors, resistors, integrated circuits, and capacitors.
