TURCK MZB Zener Diode Barriers
MZB series Zener diode barriers are designed to effectively

limit excess energy before it reaches a hazardous area. The barriers provide

convenient removable terminals within an extremely efficient and space-saving

design with channels as small as 6.3 mm wide. The barrier series features a

bussed power feed and offers both relay and solid-state switch models.

Each channel of the barriers is fitted with two stages of

pulse-tested Zener diodes and an infallible terminating resistor. If an

electrical fault such as an overvoltage occurs in the non-hazardous area of the

barrier, the Zener diodes limit the voltage available to hazardous area

circuits, while the series resistance limits the current. Within this circuit

is a fuse designed to immediately and safely rupture if the excess energy

continuously applied to the barrier exceeds the design criteria for the loop.

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.
