Digital Equipment Controller

By providing two programmable outputs, our “Digital Equipment Controller” (DEC) series offers a wide range of possibilities for controlling a variety of equipment including forestry, construction and industrial equipment. The analog input DEC models provide a standard tachometer RPM display as well as hour meter and voltage readouts by simply pushing the program buttons.

The CANbus J1939 DEC model can read engine parameters directly from the engine’s ECM, while at the same time controlling the equipment’s run rate. Operating on either 12 or 24 VDC, these units can fit into most applications. The combination of a custom connection harness and an easy to use Mil-Spec connector allows an operator to be set up and running within minutes. Available in three models: DEC-12V & DEC-24V (Analog) / DEC-J1939 (CANbus).
