Festo has announced that it will be demonstrating at IWEX 2009 how its latest modular controllers and actuators enable system designers to use a task-optimised blend of electrical and pneumatic technology for process control, to help minimise cost and maintenance overheads. The latest additions to the company’s renowned CPX series of multifunctional electrical terminals will be on show, including a new EtherCat real-time Ethernet communications module, a new series of digital and analogue I/O modules, and a new intelligent control module known as the CPX-CMXX, which provides a PLC-compatible interface for multi-dimensional axis control. Festo will also be launching a new quarter-turn pneumatic actuator at IWEX 2009. The actuator uses rack and pinion drive technology and incorporates a number of unique features, including adjustable end positions – which makes it suitable for use with butterfly valves.
