About the 0-52861-1

0-52861-1 Firing Circuit Board

The 0-52861-1 is a PCB (printed circuit board) fabricated by Reliance Electric for use within the company’s various drives.

The 0-52861-1 is used as a Firing Circuit Board.  This component is comprised of a printed board and an attached faceplate.  The faceplate is empty besides locking set screws located at the bottom and the top of the panel.  These screws are used to latch the module in position within the rack system. Set screws are normally finger tightened to prevent damage to the board or difficulty in removing the component at a later date.   This panel also has a printed red “WARNING” with a left facing arrow. Underneath this is the notation to “Check frequency jumper on VSA-Card at left before drive is first run.”

The board portion of the 0-52861-1 includes a large bipolar transistor mounted on top of a heat sink.  One of the poles of this component connects to a surface wire. This is mounted to the board using two screw connections.  There are five smaller transistors, thirty-two integrated circuits, metal film, and carbon composite resistors, ceramic disk capacitors (about 17,) and capacitors made from other materials.  ICs include OR gates, inverters, serial in/serial outs, and AND gates. Several single-pin connectors are used. The rear surface is marked with codes 802286-82A and PEC 508 852.

More information regarding the 0-52861-1 Firing Circuit PCB may be found using Reliance publications like product manuals or series user guides.  The 0-52861-1 is sometimes listed as a Baldor Reliance component. It may also be listed as coming from ABB/Asea Brown Boveri.
