About the 0-55320

The 0-55320 is a RELIANCE DRIVE BOARD 460V DV/DT card by Reliance Electric. The 0-55320 has seven large silver metal thick film resistors that run the center of the circuit board. Above these thick film resistors are nine metal tabs that are labeled with numbers: five hundred and forty-seven (547), four hundred and forty-five (445), three hundred and forty-five (345), two hundred and forty-five (245), four hundred and forty-seven (447), three hundred and forty-seven (347), two hundred and forty seven (247), forty-seven (47), and forty-seven (47). Below the thick film resistors are four more metal tabs labeled: forty-five (45), one hundred and fifty-three (153), fifty-two (52), and one hundred and fifty-one (151). There is a black wire, a brown wire, a light blue wire, a yellow wire, a gray wire, and a light purple wire that connect to various parts of the circuit board and have the color marked where they are connected: BLK, BRN, BLU, GRY, YEL, VIO (for the light purple wire). All of the wires are bundled together with zip ties and are placed into a female connection clip harness. The 0-55320 also has twelve light blue carbon film resistors around the lower edge of the card. The left edge of the card uses letters to mark out the grid lines while the upper edge uses numbers to mark out those grid lines. The numbers are increased by five and the letters go from A through Z then double up AA through AY with only the second letter being changed.
