They provide versatility and mobility. And most importantly, they are designed and built to operate in environments that commercial com- puters would never survive, such as a quarry environment. GammaTech's Durabook rugged com- puters are specifically designed to meet challenges and provide cost-effective solutions for field service profession- als' mobile computing needs. "Durabook computers come survival tested to withstand the daily doses of drops, bumps, moisture, dust and other aspects of working in the field," explained Tom Wang, GammaTech president. "They easily handle those bumpy rides over tortuous roads and paths that pass as roads. They work effortlessly in challenging harsh envi- ronments. They don't sweat the heat or turn numb in the bitter cold. They are an indispensable necessity for any field services job that requires working in inhospitable environments." Wang specifically mentioned three Durabook models that are ideal for the field services industry: the R11 tablet, and the SA14 and S15AB notebooks. Each, he said, offers the functionality, durability, capability and mobility nec- essary for field service workers to do their jobs. Mobility is a key ingredient in a rugged computer. After all, if the unit cannot be easily taken to the worksite and be able to function as a computer in an office setting does, it isn't much good. GammaTech, www.GammaTechUSA. com, 800-995-8946 Littelfuse Introduces Motor Protection Relays with Wireless Monitoring Littelfuse Inc., introduced a next-gen- eration motor-protection relay designed to enhance worker safety while allowing for faster, easier control and trouble- shooting. The MP8000/MP8100 Series Bluetooth-Enabled Motor Protection Relay allows maintenance personnel to communicate with the relay from up to 30 ft. away using a mobile app. It is the first fully programmable motor overload relay to offer integrated Bluetooth capabilities; earlier types required the purchase and installation of separate Bluetooth modules. "The MP8000/MP8100 relay rep- resents a revolutionary advance for both motor protection and safety. Lit- telfuse is proud to have been a part of developing this important safety enhancement technology," said Charles Newcomb, product manager, Industrial Business Unit, Littelfuse. A worker can set up the relay, view real-time data and troubleshoot fault codes while the panel door remains closed to minimize potential shock and arc-flash hazards, helping to create a greater level of safety. Bluetooth communication provides a number of conveniences that improve productivity. Users save time by leaving their personal protective equipment in their locker. Motors are easier to troubleshoot when workers can stand nearby the motor, instead of next to the relay located at a distance up to 30 ft. away. Once a smartphone is securely paired with the relay, a worker can easily mon- itor system status in real time, set up the relay, adjust its settings, and review its fault history. Instead of turning knobs and scrolling through menus on a small display, workers can use a smartphone interface to interact with the relay. The app is intuitive and requires no train- ing to use. The Littelfuse MP8000 App is available on the Apple App Store and Google Play. Applications for the MP8000/MP8100 relay include conveyor systems, HVAC equipment, saws and grinders, fan motors, and pumps employed in manufacturing, oil and gas, water/ wastewater and mines. The MP8000/MP8100 relay combines the tools necessary to monitor motor overload, voltage, phase loss and rever- sal, voltage and current unbalance, power monitoring, and underload in one package. The MP8000/MP8100 relay protects any motor drawing 0.5–100 full-load amps (currents higher than 100 amps require external current transform- ers). It is designed for single- or three-phase systems with operating voltages of 90–690 VAC. Although the Bluetooth interface can be used when paired with a smartphone or tablet, the MP8000/MP8100 also features an Ethernet port that can connect to a PC or SCADA system, and supports data logging through a PC with optional LFS-MP8000 software. The MP8000 and MP8100 both offer remote wired communication via Ethernet Modbus TCP/IP; the MP8100 also enables com- munication via RS-485 and CAN bus interfaces.
