Electronic relays [india] offers solid-state relays in the year 1979, basically for exports to the united states; subsequently, it expanded activities and began catering to the huge demand in the domestic market too. The company manufactures optically coupled solid-state relays [ssrs] and input/output modules. The eri ssrs are made in standard and custom-built packages, which are totally potted and work effectively in adverse industrial environments. In addition to chassis mounting type, the new small mini series can be mounted directly on pcbs, ssrs have taster switching [order of micro seconds], longer life and high reliability as compared to electro magnetic relays [emrs] and come with a host of other advantages. The product range includes: solid state relays - available in single phase and three phase versions rated 205 a/1600 v; dc/dc ssrs rated for maximum of 150 a at 60 v dc and 40 a at 200 v dc; input/output modules - eri offers industry standard single cahnne; i/o modules that can be soldered directly on a printed circuit board or placed in sockets. These reliable eri i/o modules provide an electrically clean, photo-isolated [2500 vrms min; 4000 vrms optional], noise-free interface between programmable controllers, microprocessor and computerised machine controls and external element such as limit switches, thermostats, etc.
