Before You Buy
This board replaces Marine Air and Dometic Passport IO series power supplies. Board mounted parts and layout changed over the many years since the first version of this board was manufactured however, several features of this Board can be used to insure this is the correct board for your application. All models of these boards to be replaced by the 400 I-O have a nine-digit bar coded serial number starting with either 372 or 400. There are also board markings with PCB-372 or PCB-400 written somewhere on the board if the serial number cannot be found. The terminal block always has the outputs in the same order and there were always three sensor jacks and one 8-pin display jack on the board.
Note: Some early models of the Passport I-O series featured a heat relay that was not usually used. If your application does use this relay, the board must be replaced with our Unity Control Board Model ASY-501-09-BL and an external heater triac. Note 2: If your board number or serial number starts with 310 or 300, please see For replacing Passport II, ECU, or Cabin mate control systems for more details and components available from Micro-Air for replacements. |
