Centurion ™ Configurable Controller
The Centurion Configurable
Controller is a control and
monitoring system. Primarily
designed for engine/electric
motor driven compressors, the
Centurion is well suited for many
control applications using standard
configurations to save money
and reduce training. Additionally,
Enovation Controls can custom
design a control package to meet
exact specifications for a variety of
applications.
The Centurion continuously
monitors input signals and set
points and commands outputs to
maintain proper operation. When
an out-of-limits event occurs,
the controller will stop, shutdown or control equipment to
change conditions. The auto-start
capabilities of the Centurion allow
for start/stop based on parameters
such as pressure set points or by
digital signals.
The Centurion provides real-time
data via communication ports
to a connected display and/or
supervisory system. This advanced
system offers multiple options
for remote communications and
operation including HMIs, PLCs,
PCs and SCADA systems. The
industry standard MODBUS* RTU
protocol means greater support for
a wide variety of communication
equipment including radio and
satellite communications systems.
Features of the Centurion include:
• Fully configurable control and
monitoring system. Applications
include reciprocating/screw
compressors and pump systems.
• Expandable system to meet
most three-stage compressor
applications.
• User configurability with
Windows-based software allows
the operator to point and click to
implement standard processes.
All I/O points can be custom
configured.
• No programming experience
required.
• Local and remote
communications, MODBUS RTU via
RS485/232.
• USB 1.1 support for laptops
without a serial port.
Basic Components
The Centurion consists of a display module, a main I/O module and
optional expansion I/O module. No special cables are required. The
Centurion is designed for use within a weatherproof enclosure only.
