ABB introduces its latest generation of process controller and indicator instrumentation. Called ControlMaster, the new line-up includes four models that are highly intuitive and powerful, as well as easy to operate. A comprehensive portfolio of capabilities makes these units suitable for a wide spectrum of industries. Flexible I/O capabilities greatly simplify model selection. Each ControlMaster model can be scaled to suit basic to advanced application requirements by the addition of plug-and-play function keys. ControlMaster’s full-color thin-film-transistor (TFT) liquid crystal display clearly shows process information and provides unsurpassed ease of use. Menus and operator prompts display in full text. Formats include dual-loop displays and historical trending. A sampling of the controllers' functionality includes:
•  dead-time compensation
• adaptive, predictive, and dual-loop control
•  cascade, feedforward and ratio control
 • math and logic
•  totalization
•  delay timers
 problem-solving diagnostics
The new units offer flexible communications: Ethernet, Profibus and Modbus protocols. Enclosures provide IP66 and NEMA4X environmental protection.
