New Range of Relay Interface Modules (Type 39 Series) from Finder Delivers Unique Output Circuit Protection Feature

August 30, 2011

Finder.jpg

Finder has introduced a new family of ultra-slim relay interface modules that provides a low-cost, space-saving solution for a host of industrial applications. The 39 Series MasterINTERFACE range incorporates an innovative, replaceable fuse for output circuit protection, plus busbars and terminals that substantially simplify input and output wiring.

Housed in a compact 6.2mm wide package, the 39 Series offers integral coil protection circuitry across the gamut, as well as a secure retention and ejection clip, and terminal screws suitable for blade and crosshead screwdrivers. Five dedicated module types are offered, designed to meet the specific requirements for basic, enhanced, input, output and timer interface functions.

Available with electromechanical or solid state relays for general interfacing applications, the MasterBASIC features common link supply terminal positions, allowing the use of a 16-way jumper link. The enhanced MasterPLUS module adds the option of a quick connection replaceable output fuse and special leakage current suppression versions to mitigate any detrimental effects caused by residual current in the input circuit. Both the MasterINPUT and MasterOUTPUT incorporate additional busbar jumper links and terminals necessary for the full connection of 2- or 3-wire input devices and output devices respectively, thus reducing component cost, time and panel space. The MasterTIMER is a multi-function and multi-range device with DIP-switch selection of 4 time scales and 8 functions, with timer delay adjustment achieved via an easy-to-access rotary knob on the top surface of the module.

A range of accessories is available to support the 39 Series relay interface modules, including red, blue and black 16-way jumper links, and dual purpose separators (1.8mm or 6.2mm) for the visual or protective separation of groups of interfaces operating from different supply voltages, or for the protection of cut ends of jumper links. The MasterADAPTER permits the easy connection of A1/A2 terminals of up to 8 MasterINTERFACE modules to PLC outputs via a 14-way ribbon cable, plus simple 2-wire power supply connection, providing significant wiring savings.

New Schaffner Sinusoidal Filters Type FN5040/45 Ensure Cooler and More Reliable Drives

August 16, 2011

Schaffner 225_31.jpg

The FN5040/45 sinusoidal output filters reduce the extra losses in AC motors and help to prevent premature failures and expensive downtimes. They are precisely matched to the technical requirements of modern drive systems and are particularly impressive when used with long motor cables.

With the introduction of the FN5040/45, Schaffner, the international leader in the fields of electromagnetic compatibility and power quality, is further expanding its range of products for improving reliability in motor drive technology. The new sinusoidal output filters smooth the modulated output voltage of modern drives and provide the motor with a clean sinusoidal voltage with low residual ripple. This largely prevents premature ageing or destruction of the AC motor due to high dv/dt, over-voltages, bearing currents or overheating due to extra losses. Expensive downtimes are avoided, and premature service or repair is eliminated.

The new filters are available in a compact open frame design (FN5040) or as a user-friendly packaged version (FN5045 - IP20). The cable-shield support brackets integrated into the housing facilitates work for the installer and favours savings of installation time and costs. Easily understood application instructions allow it to be safely used even beyond standard specifications, for motor frequencies up to 200 Hz or motor cable lengths up 2000 meters. Both models are designed for rated currents of 4.5 to 1200 A and for networks up to 3x 500 VAC (+/- 10%). The UL listing is currently in preparation.

Applications in building technology (pumps, fans, HVAC) benefit equally from the use of the new sinusoidal filter, as do industrial applications with very long motor cables or with several motors connected in parallel.

Cherry Brand DK Series High Performance Sub Subminiature Switches are Sealed to IP6K7 for Challenging Environments

August 10, 2011

2009 LOGO.jpg

The Best Switches Come In Small Packages

Leading designer and manufacturer of switches, sensors and controls, ZF Electronics, has launched a new series of sub subminiature switches which suit applications as diverse as automotive door latches, industrial locking systems, outdoor equipment and hand-held control units.  Demands on electronic components for increased reliability and functionality increase year on year, together with the need to achieve higher specifications within ever-shrinking housing sizes.  The new DK sub subminiature series from ZF Electronics provides the smallest dimensions and highest performance for a snap switch in its class.

DK switches are less than 15mm in length and are sealed to IP6K5 (IP6K7 on request) for use in wet or dusty environments. With temperature ratings of up to 105degC, they are extremely reliable, with a long mechanical life of over 500,000 actuations. Additional actuators are available in a choice of either simulated roller or plain stainless steel and can be operated vertically or via customised actuators.  DK switches offer long over-travel features (1.3mm minimum) and have a variety of connection possibilities with solder, PCB terminals or pre-wired options all available.

Standard DK sub subminiature switches are designed for use on low-voltage DC circuits - nominal current rating is 5mA up to 2A. Non-standard versions are also available for circuits up to 60VDC, for example for use in battery-powered equipment.  Very low voltage applications are also possible, such as the switching of thermo-couples.  Contact configuration is single pole, dual throw (SPDT) with the benefit of AuAg crosspoint contacts for high contact stability. DK series switches can also be ganged for multiple use.
