akwaman, Nicely explained, I agree totally with all the points you've made. I wanted to use SSRs(solid state relays) in wireless Hunter Fan Ceiling Controls but management was against it because of cost. As you discussed in your post, yes the intial cost investment is somewhat pricey but the ROI would have been substantial in terms of reduced customer warranty claims due to failing electromechanical relays. I'm definitely will be sharing this article with my Control Systems class at ITT Tech.

 I couldn't agree with you more, naperlou. Solid state is the way to go whenever is makes sense, as far as I'm concerned. In noise sensitive data aquisition matters, electromechanical relays can introduce unwanted noise into a system.  These kinds of optical relay technology has many uses.  Of course the obious power savings is a plus as is the reliability factor.

Whenever a solid state component is available it will generally be superior to an electromechanical one in most modern applications.  I ran into this years ago with amplifiers for communications for satellites.  Typically klystron tubes were used.  Advances in solid state amplifiers allowed the replacement of these in many cases.  They were more reliable, lighter and used less power.  I see the same thing with this class of relay.  They also, as is pointed out, avoid some of the pitfalls of electromechanical relays.  There was an article in Design News about a problem with such a relay recently.

It seems that gears have been around forever -- what could be new?
The use of ZNE technology buildings not only reduces cost and creates renewable energy, but it can give a boost to the economy. The implementation and execution will require a workforce, which means the result can be increased employment.
The use of CFD is more profound in automobile design because of the diverse physics involved. It can be used to optimize components for downsizing and reducing the environmental footprint while maintaining or improving operational efficiency.
A Detroit automaker was struggling with a semi-manual, labor-intensive parts receiving process. Workers had enter parts into a spreadsheet manually at a stationary workstation. This stopped the receiving process dead in its tracks. A better system was needed.
Pressure sensors can be used in a wide range of applications. It’s imperative that they’re suited for use in hazardous situations and are fully compliant with one of several protection standards.
