Weidmuller introduces the new WavePak dc/dc isolator — a cost-effective, adjustable conditioning solution for applications with high-level signals, such as flow transmitters in process applications. WavePak is designed to interface between field equipment and control systems, converting and isolating signals with a high level of accuracy that exceeds 0.1%.
The device is a four-wire dc isolator with complete three-way isolation. Voltage or current inputs and outputs can be internally selected, and are easily scaled via pushbuttons located on the front of the module. Outputs can be configured as direct or reverse action, as required by the application. It gives users the ability to select either current sink or loop-powered input mode, allowing the module to be an active or passive input circuit. 24 V dc power for two-wire transmitters also provides the flexibility to drive additional load in an active input loop, which simplifies field wiring and reduces the need for field device power supplies. High-level 3-port isolation between input, output and supply ensures signals are protected from electrical interference and ground loops. It has a space-saving 12.5 mm wide design, mounts on TS35 DIN-rail and features both CE and cULus approvals. From Control Engineering , read 10 tips for better grounding .
Weidmuller: The product's features simplify installation and reduce system commissioning and maintenance time. Unique integrated test terminals allow testing of input and output current values without removing cables. LED indicators display the signal status, for quick and easy trouble shooting and maximized system uptime. Weidmuller’s high quality, pluggable field terminals allow quick-release and provide the most secure connections available. WavePak DC/DC offers application flexibility and cost savings at every turn. Supplied from any auxiliary voltage from 12 to 60 V dc, it can drive output current loads. This feature allows additional devices, such as local indicators and chart recorders, to be powered in the same loop without additional power supplies.
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.
