Solid-state overload relay
This solid-state overload relay provides enhanced motor protection and motor energy consumption information, helps users improve energy efficiency and protect electric motor investments.
The Allen Bradley Bulletin 193-EC5 E3 Plus solid-stateoverload relay combines current and voltage protection with enhanced powermonitoring and diagnostic capabilities for safeguarding critical electric motorloads. The new overload relay is designed for low voltage applications inmaterial handling, water/wastewater, process, petrochemical and minerals andmining. The ability to provide current, voltage and power-quality informationof a specific motor helps speed troubleshooting, minimize downtime and reduceenergy costs.
The overload relay identifies motors contributing to themonthly peak demand and power factor line items on utility bills andcommunicates this and diagnostic information using DeviceNet and RSEnergyMetrixsoftware. It also assists in activity-based cost accounting and verifyingenergy-reduction initiatives. In addition, the overload relay is equipped withAllen Bradley DeviceLogix Intelligent Component Technology, which integrateslogic-solving capability into the overload relay. This provides users with basicdigital control when a programmable controller is not available. It also can beused to turn off a motor in the event of lost communications within a controlsystem.
The relay also helps protect against voltage issues such asunder voltage, voltage unbalance, phase loss, frequency and phase rotationbefore the contactor coil is energized. While the motor is powering a load, theoverload relay protects the motor based on excessive real power, reactivepower, apparent power and power factor. The relay accommodates currents rangingfrom 0.4 A to 860 A, as well as currents up to 5,000 A using external currenttransformers.

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.
