The iGUARD™ is one controller for all your
engine-driven generator set applications. It is
designed from the ground up to work with
today’s electronic engines, accepting the J1939
protocol. The iGUARD™ also works with non-
electronic engines. 
Designed to meet NFPA-110 and NFPA-99
requirements the iGUARD™ has ample inputs
and outputs. 
The new iGUARD™ controller can be used for
all gen-set applications: single-phase or three-
phase, and 12 or 24 V. 
Engine speed can be read from a magnetic
pickup,AC generator frequency, or J-1939
CANbus.

Because the microprocessor is flash-based, the
controller can be easily re-programmed or
updated using a PC in the field.
