I have SC5-S-DC6V relay. It says 7A, 240VAC,50Hz and coil:6VDC. Then again after a long separating line, there is 10A/125VAC. Will this do?Yes, if you have a 6V power supply with which to drive it, if you only +5V then answer would be "probably". Make sure the contacts are rated for over 150 VAC so then can withstand the ringing voltage.
The BC547 should have much less than a volt from collector to emitter when the relay is on if it is working correctly, so in that case lowering the 1k resistor would have very little effect. The best thing to do is to measure the collector-to-emitter voltage.i don't actually need the decoder. I just want to switch the line using call accept/end function.
there is BC547 transistor feeding the relay via 1kOhm, do you think lowering this resistor value will increase voltage for the 6V relay?
