Bangalore-based electronic relays [india] offers a range of solid-state relays [ssrs] in dc/ac and ac/ac [opto-isolated] versions for various industrial uses. Some of the salient features are: opto isolation 2500 v ac; input: ttl/cmos compatible; output: triac/scr-scr [no/nc configuration]; zero voltage turn on/random turn on; safety cover for 001 series [at extra cost]; reverse voltage protection for dc/ac relays; built-in snubber; terminal pins are polarised to prevent reverse plugging; chassis/pcb mountable; and led indicator [optional].
