Re: Go solid state

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.

If we are going to be creating a network that serves us, one of its most critical nodes will need to be ourselves. This is where wearable technology comes into play.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
