Replacement A-281C Control Board | 85 to 240 Volts
The A-281C Control Board is part of a legacy DX cabin control system sold in the mid-1990s. This is a newly manufactured, footprint-compatible replacement that operates identically. The display interface can use either the legacy 4-conductor cable with Molex connectors on each end or the newer 6-conductor RJ-12 cable with straight-through wiring.
Note: Shown with Pin Connectors (most units before 1999).
Guides & Information
Before You Buy
This board was used in Cruisair systems in the 1990s and early 2000s. Original boards measured 7” x 6.25” [17.8cm x 15.9cm] and featured a four-pin display jack and three-pin sensor jack, usually protruding through an opening in the enclosure. A distinctive line of spade connectors ran along one side of the board, spanning the entire length.
Original boards were typically marked with the number 42403 and often had either A-281C or A285 marked as well. This board replaces Cruisair part number 42403 and Dometic part number 701800007 control boards. It also features the newer six-pin display connector, allowing an upgrade to the SMXIIir display without needing an adapter.
