Basically what I need to do is I need to have a constant signal (gnd or 12v) whenever a different wire is disconnected from ground..

One way is the DEI 502T closed loop sensor. This will do it fine, except I can't find out anywhere if it's a latched output or just a timed outupt.

Also could use a PAC TR-7 to do the same thing, but again it's a timed output and I need a latched output..

I could do this rather easily with a relay, BUT I can not have the relay drawing current all the time like it would have to be setup that way.

Any suggestions, or anybody know if the 502T is a latched output or pulsed???

 

the 502T is pulsed I bielve

The wire that is getting disconnected from ground, what is it hooked up to. Does the polarity change when it is disconnected from ground. If I had a little more imput on this i could probally figure out a way to do this for you.

I.E. what are you trying to do in the first place

 

Hey

If your load is low current, Omron makes a few models of latching relays - one coil to open, one to close. They only require a short pulse to activate. I thnk the ones I have are good for 1.5A resistive load, but they are PC board mount.

Good luck, J
