As you can guess from the question I have no knowledge of Electronics but I do need help.
Are there different diodes for AC and DC?
I have a system (Irrigation)that worked on manual operation for years on 24VDC with no problems from the diodes.
Recently I changed it to 24VAC so that I could incorporate a programmable timer .
The diodes are used to stop current backfeed on the common pump start circuit and various warning lights.
The diodes function perfectly on 24VDC but fail(permit backfeed) on 24VAC.
The backfeed readings Im getting on the diodes are
24VAC input 24 VAC backfeed 13.7VAC
24VDC input 24VDC backfeed nil
These readings were from loose diodes (Straight out of the pack and not put in the circuits)
Can anyone help
Thanks
