DC20D is a controller for diesel generator sets. It has automatic start and stop, protection and alarm indication functions. The panel contains DC power supply and operating status indication functions; the monitoring part includes fault indications for overspeed/overclocking, over-generator voltage, low oil pressure, high water temperature, low water level, start failure, parking timeout, emergency stop alarm and low battery voltage, and more. It is helpful to judge the status of engine and generator.

The output contacts use relays, which can withstand large output currents, and system parameters can be set according to the buttons to meet applications in different situations.
