HT-SG-50 - Speed Control Unit - InGovern Series

The HT-SG-50 is a simple and cost-effective electronic speed governor for conventional diesel engines. Its digital processing not only provides flexibility in configuration but also allows CAN J1939 data exchange with many modern controllers.

The unit will internally convert the signal from a standard inductive flywheel pick-up to an RPM value, display it on the 4-digit LED display and also send it as a standard J1939 value to a connected controller.

The HT-SG-50 is supplied pre-configured and once the number of flywheel teeth is input (1 x press of [Fn] button then [+] or [-] until the correct value is displayed) then the engine will run. All parameters are stored in non-volatile memory.
