Zener diode barriers
Zener diode barriers are designed to effectively limit excess energy before it reaches a hazardous area.
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.
