SPS IPC Drives 2013 exclusive show report

06 January, 2014
include: a small transponder-coded safety switch (CES-AR-C04) with an AR interface for connecting up to 20 switches in series; and a Unicode version of its CES-FD field evaluation system for connecting to CKS safe lockout mechanisms.

At SPS, Festo was demonstrating a safety module (CAMC-G-S1) that allows Safe Torque Off functions to be achieved in its CMMP-AS-M3 motor controls. When used with the CMGA safety system, Safe Stop functions SS1 and SS2 and safely-limited speed (SLS) can also be achieved.

Hima Paul Hildebrandt previewed an expansion of its HiMax safety system for small-to-medium applications. The X-CPU 31 processor combines CPU and system bus functions in one module, saving costs and increasing the number of module slots available. The module uses secure communications via safeEthenet.

Kübler is offering a maintenance-free, contactless slip-ring system for transmitting up to three load and three signal channels in hygienic and packaging applications. The encapsulated, IP64-protected SR1085 slip-ring (above) is said to be easy to service. The 800rpm device can handle currents up to 25A.

Leuze electronic has released two ranges of safety light curtains designed to meet the connection requirements laid down by Aida (the Automation Initiative of German Automotive Manufacturers) which represents the big German car-makers. The MLC 511 (SIL 3, PLe) and MLC 311 (SIL 1, PLc) light curtains have four-pin M12 plugs and are designed to operate in IP6X environments. Leuze is also integrating Profibus interfaces in to its CML 700i measuring light curtains.

Leuze has also redesigned its MSI safety relays and fitted them with interchangeable plug-in terminal blocks that allow users to choose screw or spring-cage terminals.

Lovato has a new range of pushbutton control stations for up to six actuators, and offering IP66, IP67 or IP69K protection. The LPZ stations use screw and cage-clamp spring terminals. Also new is a range of industrial MCBs (miniature circuit breakers) with a choice of operating curves and capable of handling currents up to 125A.

Mitsubishi Electric has developed a range of compact MCCBs (moulded-case circuit-breakers) with high breaking capacities. The WS-V MCCBs are available in three sizes, as three- and four-pole models for fixed or plug-in installation. A German firm called Sedotec has developed a range of modular LV switchgear cabinets which, when used with the WS-V MCCBs, have passed tests including the type tests defined in EN 61439-2. Preassembled Vamocon cabinets containing the MCCBs thus offer Asta certification and conformance to EN 61439-2 as standard.

New from Pilz is a range of flexible, multifunction light barriers that allow muting, blanking or cascading to be carried using just one barrier. The PSENopt Advanced barriers, which comply with PLe, use single continuous light beams that make dead zones impossible and can be used close to an application, thus saving space.

It is now possible to implement interlinked, decentralised safety systems with tree or ring topologies using two new link modules for Pilz’s PNOZmulti 2 system. The PDP modules (above) can communicate signals from sensors to base units, while the Multi link modules support data exchange between multiple base units. The modules can be configured using the PNOZmulti Configurator tool.

Rittal is offering an alternative to costly dedicated industrial displays with a range of enclosures that house office-type TFT displays and protect them to IP65, thus shielding them from exposure to dust and water jets. The sheet-steel housings can accommodate widescreen TFT screens up to 24” and protect them behind a pane of safety glass.
