8280-423 digital boat speed controller

The 723PLUS Model 8280-423 is for twin engine marine applications requiring mechanical load sharing. It regulates the load and speed of diesel engines used in such applications, including those with elastic couplings. A Magnetic Unit Unit (MPU) or a proximity switch can be used to sense engine speed through the controller’s dual speed signal input. The 8280-423 contains many functions. This includes features such as single throttle operation, flexible coupling twist filtering and several functions for fuel restriction. Woodward 723PLUS Manual 02881 contains complete details of all features available with the 8280-423. There are several types of I/O for this speed control, some of which are configurable. Two alarm relay outputs are user configurable with 13 states to choose from, and the communication port supports a handheld programmer for monitoring and programming control. Two additional communication ports provide redundant communication for proper loading and clutching.
