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.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
