This electrical schematic details a 125Vdc power supply feeding into a partial SEL-3350-A1 controller module. The circuit includes an upstream fuse, bus protection trip and relay fail alarm connections, and an arrangement of digital inputs and outputs labeled A01 through A24. Terminals connect through specific relay contacts and discrete points designated A through J on the TS-3350 terminal strip. Grounding is provided at terminal Z07.
