Courtesy: WeidmullerWeidmuller's DIN-rail mounted Varitector VSPC surge protection is a streamlined solution to protect control panel equipment from damage and breakdowns due to local lightning strikes. It is a means to effectively manage the protection of signal circuits in Control and Instrumentation applications.

Weidmuller’s Varitector VSPC includes over 60 models with a robust range of pluggable, replaceable, single- and multi-channel modular surge protection devices (SPDs). Meeting UL 497B requirements, VSPC provides a combination of wire-to-ground and wire-to-wire protection. The separate bases accommodate field connections and make a ground path from the SPD, via the (grounded) DIN-rail.

Targeted at measurement, control, and fieldbus applications, typically in Water and Waste sectors, VSPC is rated for discharge currents up to 20kA (8/20μs). A combination of gas discharge tubes, varistors and suppression diodes, in single- or multi-stage configurations are used to protect nominal voltages between 5 V dc and 230 V ac. VSPCs are suitable for analog current and voltage loops, dc and ac status signals, and a wide variety of serial interface and telephone network installations. To minimize panel rail space, various VPSC models with four conductors (e.g. two analog loops) can be protected by one 17.8mm (0.7inch) wide module.

The key to ensuring full, continued protection is the VSPC status monitoring option, which shows when the SPD module replacement is needed. The arrestor condition status is displayed on the device via a green/red indicator. An optional remote display is available via a separate VSPC Control Unit, where up to ten SPD modules may be connected. Other features include colored product marking to easily identify different working voltages between a group of modules mounted together on the rail, models for protecting floating signals, and a portable test accessory (V-TEST).

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
