FW Murphy Centurion

FW Murphy's C4 Series Centurion Configurable Controller is a control and monitoring system designed for engine/electric motor driven compressors and many control applications using standard configurations to reduce cost and training.

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 change control 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.
