The Murphy Automatic Engine Controller EA150 provides you with simple–yet sophisticated, engine automation. It features basic automatic start/stop capabilities plus other features found on more sophisticated and expensive controllers–all in an easy to install panel. The EA150 operates from 12 or 24 volt systems. It includes crank and rest cycles, sensing circuit for crank disconnect and overspeed, overcrank, and re-crank on false starts. Four LEDs indicate first-out shutdown for: low pressure, high temperature, overcrank and overspeed. A fifth LED for engine running indicates when crank disconnect occurs.

The built-in oil pressure and water temperature Swichgage instruments provide visual indication and can be set to initiate shutdown on critical pressure and temperature. The electromechanical quartz base hourmeter can record up to 9,999.9 hours. It is housed in a shockproof case and built to be rugged and durable for a long life. A selector switch allows you to manually select the operation sequence.
