INSTRUMENTATION & CONTROLS
Controls Inc. has developed new microprocessor-based controllers, the C4 (left) and G4 (right) designed for engine monitoring and control
for Tier 4, SAE J1939 diesel and natural gas engines. The modules are available as stand-alone controls or as part of a complete control
panel system.
STAYING IN CONTROL
FOR TIER 4
Controls Inc. releases next-generation C4 and G4 engine control
modules for Tier 4 diesel and gaseous-fueled engines
BY DJ SLATER
Controls Inc., the Medina, Ohio, manufacturer of engine and generator set control
systems, has developed a new series
of engine control modules for Tier 4
interim engines. The C4 module is
suited to a wide array of diesel and
natural gas applications, while the G4
is specifically for generator use.
These controls are an extension
of the existing C series product line,
according to Controls Inc. President
Bob Cowen. “The C3 addressed many
needs in the engine control market,”
Cowen said. “And the C4 and G4 build
on this success with more features,
flexibility and emissions support.”
Employing advanced micropro-
cessor designs and environmental-
ly rugged packaging, the modules
boast simple, self-contained inte-
gration into equipment ranging from
basic power units up to sophisticat-
ed schemes that previously required
additional modules, the company
said. “Adding relays, PLCs and tim-
ers to panels adds expense and
complexity that integrators can’t
afford,” Cowen said. “Our modules
eliminate these headaches and cut
the variety of products needed to
serve customers.”
The C4 control is designed to offer
an unprecedented level of integra-
tion in a single model. Able to control
mechanical, Tier 3, Tier 4 diesels,
as well as spark-ignited engines,
the C4 is a complete package, the
company said. Controls’ exclusive
programmable input and output tech-
nology enables users to configure
the analog inputs, digital inputs and
relay outputs to a wide array of func-
tions without the need for external
computers or extensive training, the
company said.
