Product Overview: 

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.

A fourth input is connected to a speed calibration potentiometer during set-up mode only. DIP switches allow selection of normal/set up mode and two speed input ranges. An LED gives indication of operating mode and CAN bus activity.

MeCAN is compact and light enough for inclusion in engine wiring harnesses but can also be surface mounted. The case is fully sealed in epoxy resin for high impact and environmental resistance. Two standard versions allow use with either fault switches or Murphy ES series resistive senders. Custom solutions are also available for non-standard, volume OEM requirements.
