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
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
