Description

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.  

The eGUARD can be configured to automatically
or manually operate most types of applications,
from a simple start/stop sequence to complex auto-
matic throttling.  Pumps, Compressors, Chippers,
Grinders and Power Units are just a few of the ideal
industrial applications for the eGUARD.  
The  eGUARD controller can maintain constant
pressure, flow or level by automatically increasing
or decreasing engine speed. 

Features

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

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.

*

(when supported by the ECU manufacturer)

Compatibility: Accepts Magnetic Pick-up (MPU)

or ECU J1939 speed signals.

Field Configurable: Allows password protected

configuration changes through the keypad.

Field Programmable:  Flash-based microprocessor

allows for easy upgrades or reconfigurations
using a PC or laptop.

Sealing: Maintains NEMA4 and IP65 rating when

properly mounted in a rated enclosure.
