The MeCAN™ is a compact, encapsulated interface module that translates resistive sender, fault switch and speed signals into SAE J1939 CAN bus data.
MeCAN allows quick and simple integration of mechanical engines into modern CAN bus systems. Applications include the retrofit of older engine fleets with modern digital instruments, controls and telemetry, engine hour tracking and the development of standard control panels for mechanical engines. MeCAN has three sensor inputs and one output. Two inputs are for oil pressure and coolant temperature sensing, either by fault switches or resistive senders. The third input measures engine speed using a magnetic pickup or charge alternator signal. Input signals are translated into SAE J1939 CAN bus messages with assigned PGN address, data scaling and transmission rate. The output can drive an alarm lamp or buzzer or actuate a shut-down relay if the pressure, temperature or speed inputs deviate outside preset fault limits.
