Centurion Configurable Controller
Centurion Configurable Controller


The C4 Series Centurion Configurable Controller is a control and monitoring system. Primarily designed for engine/electric motor driven compressor, the Centurion is well suited for many control applications using standard configurations to save money and reduce training. Additionally, Murphy can custom ensign 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 allows 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 supervisor system. This advanced system offers multiple options for remote communications and operation including HMI's, PLC's, PC's, 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.
