Cost saving control solutions for the water industry

26 May 2009

Festo has launched a series of products, including modular controllers, real-time communications modules, sensors and actuators that enable system designers to minimise cost and maintenance overheads.

Festo’s CPX series multifunctional electrical terminals provide system designers with a flexible, modular approach to process control, monitoring and diagnostics.

The terminals can form part of centralised, decentralised and hybrid control schemes, and their module content can be freely changed at will, enabling systems to be reconfigured or expanded without altering the wiring. A wide range of compatible modules includes integrated PLCs for distributed control, intelligent analogue I/O units for temperature sensing and signal detection, PNP and NPN digital input units, M12 and M8 connection blocks, and connectivity to virtually all leading bus systems. Festo has expanded its CPX system versatility by providing DTM files for PACTware connectivity.

The CPX-FB38 module further extends the fieldbus connectivity of CPX series electrical terminals by adding EtherCAT real-time Ethernet communications. The module features two EtherCAT ports and an integrated Ethernet switch for maximum installation flexibility. The flexibility and cost-effectiveness of the CPX Integrated terminal and valve manifold control system makes it an extremely popular choice for controls and systems engineers.

Festo has also launched a powerful quarter-turn pneumatic actuator. The actuator is a rack and pinion drive which ensures a constant torque characteristic across its entire 90 degree rotation angle. Available in single-acting and double-acting versions, DFPB series actuators offer a unique level of versatility – the same units can be used for clockwise or anti-clockwise operation, simply by inverting the drive. Pressure relief slots on both faces enable the actuators to be universally fitted to a wide range of valves and feature adjustable end positions – which makes them ideal for use with butterfly valves. There is a choice of 7 sizes of single-acting and 10 sizes of double-acting actuators; the largest model can generate up to 270 Nm of torque.
