You can do with a SSR. Check out International Rectifiers site on SSR apps. The disadvantages of an SSR compared to a EMR (electro-mechanical relay) are the increased voltage drop, significant power dissipation at higher currents (due to say RDSon), off state leakage , and it is difficult to switch small signals like Audio. Of course the advantages of a SSR are the long life, reduced EMI/RFI (no contact arcing here) , fast response etc. Madhu (n8tzf) -----Original Message----- Has anyone used one of the solid state relays in a situation where the ssr is used to keep a piece of equipment on and then used as a reset to turn it off and then back on after a delay ? Or would this type of use warrant a relay rather than a SSR Eddie turner, kc4awz -- http://www.piclist.com#nomail Going offline?
