2.0 Overview
The Centurion configurable controller is a control and monitoring system expressly designed to meet the requirements of
three specific kinds of applications: Screw and Reciprocating Compressors, and Pumps. To that end, it is able to satisfy
the particular needs and inevitable variations that exist in real world applications because the Centurion controller is enor-
mously flexible and configurable within fixed parameters. The Centurion controller is a system designed to monitor, con-
trol, protect, and optimize small to medium sized gas operated compressors and pumps in the field by monitoring set
points and digital, analog, and thermocouple input points and providing the logic to take corrective and/or proactive
steps to maintain proper operation. The Centurion controller also allows for controlled shut down and no-flow monitoring
as well as expanded and auto start up, and engine control capabilities, which are so critical to the systems the Centurion
controller is designed to protect.
The Centurion controller provides real-time data via communications ports to a connected display and/or supervisory
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 protocol means greater support for a wide variety of commu-
nication equipment including radio and satellite communications systems.
The heart of the Centurion system is the Main Input/Output (I/O) Module, known as C3-1, which can be mounted on a
standard DIN rail. While it is designed to work with any Modbus (Master) compliant HMI (Human Machine Interface) or
with no operator interface at all, it is optimally configured and field-configurable through MConfigPro, powerful software
developed to configure the controller. Parameters can be modified through C3-3 Display, F W Murphy’s specially pro-
grammed controller display, in the field without special need for laptop or software.
Basic Components and Key Features of the C3
TM
Series
The C3 Series consists of a Display Module, a Main I/O Module, and optional Expansion I/O Module. No special cables
are required. The Centurion system is designed for use within a weatherproof enclosure only.
■ Display Module (C3-3 Head): 128 x 64 LCD graphic display; (-40 to 85) °C
■ Main I/O Module (C3-1):
• 32 Digital Inputs (DI)
• 10 Digital Outputs (DO)
• Separate direct input for Analog and Thermocouple inputs:
– 12 AI on the Centurion C3-1
– 8 TC on the Centurion C3-1
• 1 Magnetic Pickup (MPU).
• C3-1-A: Same as C3-1, plus two (2) Analog Output (AO).
■ Expansion I/O Module (C3-2) as required: 8 AI, 8 TC, and 4 AO
Optional Components:
The C3-1 hardware may be configured with 2 analog outputs and it may be augmented through an Expansion Module
(C3-2) which provides analog outputs and additional analog and thermocouple inputs.
C3-1-A with Analog Outputs:
■ 2 Analog Outputs
C3-2 Expansion:
■ 8 Analog Inputs
■ 8 Thermocouple Inputs
■ 4 Analog Outputs
