Transformer-isolated intrinsically safe barriers integrate marshalling, signal conversion/isolation, and intrinsic safety in one module. Knife disconnects and testpoints are designed into a base terminal block which accepts pluggable electronics for input and output signals from hazardous and safe areas. The process-interface terminal block is 12.4 mm wide and can be DIN-rail mounted. Bridging is possible using insertion bridges. The galvanically (transformer)-isolated electronic plugs are coded for both hazardous and safe area applications.
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
