Automatic Genset Control Modules
The automatic Genset control modules provide complete automatic control of
standby gas or diesel generator set engines. All fuel, ignition, and alarm relay
controls are via heavy-duty industrial type relay contacts eliminating the need
for external control power relays.
Many different models are available depending on your needs. Scroll down to
read a general description of each of our four different levels of automatic
control modules. More specific features are listed by model. Select any model heading below to view / download complete model specification data sheets, operating instructions, and typical wiring
diagrams.
For convenience, use our
Selection Guide to assist in choosing the
correct engine control for your application.
We offer many more special models (not listed here) which usually consist of
the following basic control modules with specialized software and/or hardware to meet your
specific needs. We welcome the opportunity to review and discuss your specific
requirements.
Note: The word "Level" used in classifying our controls (i.e. Level 2)
refers only to the relative level of complexity of each product family and does
not directly correspond to any other specifications.

The Level 2 Genset Control Modules are ideal for systems involving
NFPA-110 requirements, or any other application where pre-alarms or variable
start/stop time delays are desired.
The Level 2 controls can also be combined with an
Interface Adapter via a data-link cable to add many
other desirable functions including remote serial communications (RS232 &
RS485), additional I/O, battery voltage monitoring, remote annunciation, and
more. Go to the Interface Adapter section for more
information or contact us for your requirements.
