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.

ured to control engine speed using most types of
analog input devices (0-5v, 1-5v or 4-20 mA).
1 - RS485 port
●
Throttling Output: CANbus J1939* or incre-
ment/decrement relay pulse.

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.
