Features  
Here are some of the unique features only Murphy’s  
eGUARD can offer you at our competitive price.  
Standard Components

The eGUARD is a state-of-the-art controller. It will  
meet virtually all of your engine-driven equipment  
application requirements. The eGUARD has been  
designed from the ground up to control today’s elec-  
tronic engines using J1939 and can easily control  
the traditional non-electronic engines.  
8 - Analog inputs (one battery dedicated)  
1 - Magnetic pickup input  
8 - 20A Form “C” relays  
1 - RS232 port  
Throttling Input: The eGUARD can be config-  
ured to control engine speed using most types of  
analog input devices (0-5v, 1-5v or 4-20 mA).

Throttling Output: CANbus J1939* or incre-  
ment/decrement relay pulse.

matic throttling. Pumps, Compressors, Chippers,
