Attached is a simple part of a circuit I am designing. I am inputting several separate 12vdc inputs to a relay bank which is common to a solid state relay.
Each 12vdc input is also, prior to going to the extractor, to be taken to another source in a separate circuit. I want to stop the back flow of electricity to the other relays in order to only have the second takeoff portion of that particular relay operate.
After research I am putting a 1k ohm resistor in and a diode. Gee I have no idea of what diode to use. I have read a lot and think a Schottky Diode but do I go for one above 12vdc to avoid ANY feedback? And the fact I am only powering a solid state relay, one at a value of say 500 millivolts is the go??
I have no idea. First time user of an electrical check valve.
Any rapid replies would be most appreciated as I have to get this baby running tomorrow which is why I am running out of research time. 2100hrs here ha ha You guys will be in the AM.
