ELECTRONICS: Rockwell Automation expanded its overload relay family with the new Allen‑Bradley Bulletin 193-EC5 E3 Plus solid-state overload relay, featuring voltage protection and energy monitoring. Part of the E3 Plus family, the new overload relay combines current and voltage protection with enhanced power monitoring and diagnostic capabilities, helping users improve energy efficiency and safeguard critical electric motor loads. The new overload relay is specially designed for low-voltage applications in material handling, water/wastewater, process, petrochemical, and minerals and mining.
Communicating status and diagnostic information using DeviceNet communications with Rockwell Software RSEnergyMetrix software, the new overload relay identifies motors contributing to the monthly peak demand and power factor line items on utility bills. It also assists in activity-based cost accounting and verifying energy-reduction initiatives. In addition, the overload relay is equipped with Allen‑Bradley DeviceLogix Intelligent Component Technology, which integrates logic-solving capability into the overload relay. This provides users with basic digital control when a programmable controller is not available. It also can be used to turn off a motor in the event of lost communications within a control system.
The new solid-state overload relay also helps protect against voltage issues, such as under voltage, voltage unbalance, phase loss, frequency and phase rotation before the contactor coil is energized. While the motor is powering a load, the overload relay protects the motor based on excessive real power (kW), reactive power (kVAR), apparent power (kVA) and power factor. The overload relay accommodates currents ranging from 0.4 to 860A, as well as currents up to 5,000A using external current transformers.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
