RK66

The RK66 is an Auto-Maskin interface module designed to connect engine sensors, switches, and speed signals to a DCU 305 engine controller on marine and industrial engines. It provides 12 switch inputs, 5 analog inputs, and 2 speed sensor inputs, along with connections for power and speed relays, so a single module can bring the engine’s key signals into the controller. The RK66 is a required part of every DCU 305 installation, which is why a module comes with each DCU 305 kit. It mounts on a standard DIN rail and measures 242 millimeters wide, 105 millimeters high, and 35 millimeters deep, so it fits easily in a control panel next to the controller. It works with the DCU 305 R3 LT, DCU 305 R3, and DCU 305 A R2 engine controllers, and the terminals make field wiring straightforward. At about 1.8 pounds, the module is compact and easy to mount. Because Auto-Maskin has released the RK-66 with several revisions, it is worth confirming the revision and article number against your DCU 305 controller before ordering. This makes the RK66 a practical choice for marine engineers and service technicians who need to replace a worn or damaged interface module and keep an engine control system running.
