Description
MC Series MillenniumController is a PC-based monitoring, control and data acquisition system. Designed with engine-driven compressors in mind, the MC Series is suitable for a wide range of industrial applications. As the heart of the control package, the MC series continuously monitors inputs and set points for correct operation. When an out-of-limit event occurs, the controller provides an alphanumeric readout ofcritical machinery data or shutdown fault information. In addition to the shutdown and control functions, the MC series controller provides both local and remote communications of vital equipment and operating data. This advanced system offers multiple options for remote communications. A serial link is provided for Programmable Logic Controllers, PC’s and SCADA systems. Radio and satellitecommunications are accommodated through the MODBUS RTU protocol. Operations analysis and maintenance is facilitated by the operation hours and data trending system. The shutdown snapshot feature gives operators a complete picture of system conditions at shutdown.

Optional I/O Expansion Modules C267 Module UL/cUL Listed, Class I, Div. 2 Groups C & D
The C267 adds standard I/O capability to the MurphyMillennium Controllers via MODBUS RTU communication. The C267 includes 8 digital inputs, 7 analog inputs, power supply monitor, 8 discrete outputs and 1 frequency input for speed sensing.

C277 Module UL/cUL Listed, Class I, Div. 2 Groups C & D
The C277 adds temperature sensing capabilities to the Murphy Millennium Controllers through MODBUS RTU communications via an RS485 port. The C277 can readup to 18 ungrounded thermocouples or mA sources from pressure transmitters and other transmitters.

C287 Module UL/cUL Listed, Class I, Div. 2 Groups C & D
The C287 adds precision analog inputs and additional analog outputs to the Murphy Millennium Controllers via Modbus RTU communications. The C287 includes four 15-bit analog inputs, four 16-bit analog outputs (all 4-20mA).
