Product Overview:

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, FW Murphy 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, shut-down 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.

Specifications:

This Centurion consists of one C4 main I/O module, one M-VIEW® display module and the option of adding MX4-R2 and MX5-R2 expansion I/O modules. No special cables are required. The Centurion is designed for use within a weatherproof enclosure only.
