eek. Install on Saturday.
Ok, so we are using relays to switch 2 things (not high power):
Screwdriver motor 2amp 12V (fast switching 20ms burst).
Mains power to answer machine (250ms switching, once every 3 seconds (for 5 min periods on then 30mins off)).
For other elements of our installation (with lower power) we have been using tip120's & H-bridge circuts (L292D), which drive the relays.
We're looking at ssr's. Will these one's be good to use in this instance....
4-32dc control voltage
12 mA input current
4kV isolation voltage
24-265 load voltage
1.6 max on state
25A rms max load current
350 or 150 rms min load current
1.2dc release voltage
cheers for any advice anyone can lend. I think I have travelled down a cul-de-sac
