Solid-state motor starter functionality
This compact solid state device performs four motor starter functions and has a life expectancy up to 10 times that of traditional contactors.
The CONTACTRON 4-in-1 solid state reversing contactor combines four functions in one narrow package. Designed for three-phase ac motors up to 4 kW/5 hp, the 4-in-1 provides forward, reverse, overload protection and redundant emergency stop contactor functionality in a 22.5 mm-wide module. The compact size reduces the necessary DIN rail space by up to 75%, saving space and wiring costs as compared to a contactor-based solution. The unit's life expectancy is up to 10 times longer than traditional electromechanical contactors, which results in reduced maintenance costs. Integrated input/output surge protection circuits reduce system downtime, and 16 separate motor overload settings reduce inventory requirements. LED and remote indication acknowledge motor status. The unit is rated for safety category 3, SIL 3 and ATEX zone 2.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
