need help finding a component for voltage leakage from diode |
|
|
Basically I have a device that uses diodes that seends out 12VDC. There are 12 channels that are being used out of 24, which when one is fired it triggers a timer relay. My problem is that when one channel fires I am getting a small amout of current through the other channels as well. It is not much but enough to trigger the other relays. The positive trigger on the relay starts at 3 ma. I need something to block the leakage. I tried 1k resistors across the coils of the relay but it only seems to work for the first 8 channels, the next 4 still fire when one of the first 8 is fired. Also if it helps each 8 channels share the 12vdc source voltage before the diodes. Any help would be great.
