I have modified a circuit that I posted previously. I am trying to use a 5vdc output from a controller (which is protected) to reverse polarity on a 110vdc load using a DPDT relay as an H-Bridge. Can you guys review it and tell me if it is okay?
Specifically here are my questions:
1. My last thread was closed to a violation of TOS based on how the LED was connected. Does this new design correct that problem?
2. Do I need a diode across the coil?
3. How can I protect the relay? (my first one got ruined somehow but am not sure how, I want to make sure it doesnt happen again)
The relay used is this one: http://www.digikey.com/product-sear...us&keywords=PB1059-ND&x=13&y=19&formaction=on
The load that the christmas light strand pulls is 110mA @ 110 vdc
Thanks.
