has anybody used the z1011 sensors with dpdt relays like the ones you would get from mouser, etc? i know that they work with the one that zstuff sells but i’m looking for a simple way to use these sensors.
I cant seem to get the white wire from the sensor to trigger the relays. most diagrams available show control tracks, which i don’t have or want. while the 'screws" on the relay socket have numbers, i can’t get it to fire the lionel pw signal bridge.
what i have tried…
the signal bridge has number clips to which i have attached wires.
sig br Red (1)/green(3) to NO/NC on relay
sig br black(2) to trfmr common
relay is powered +/-…it has an led built in so i know it is working
the sensor red/blk to power +/- like the relay and it works as it is supposed to…red/gree/red when the sensor is covered
sensor white doesn’t do anything when i attach the wire to anything else. just makes the red/green lights both come on. If i leave the white unattached, the gr goes red as it should when the sensor senses something. Just can’t get it to trigger the bridge from green to red? Any ideas?
When I first built my layout I tried to use the DZ block style IR sensors with a Radio Shack reed type relay without any luck. After talking to Dennis at Z-Stuff, and his checking into it, it was determined that the circuitry for the sensor requires using the DZ relay. Gave it a try and haven’t had any problems in over 5 yrs.
I was hoping to use relays with the scokets with screws. the scew-type connection is easier for me to manage than the wire-twisting type that he offers. Plus the standard type relays are easier and cheaper to obtain.
Well i guess one can’t have everything. I’ll try to figure something out with euro connectors.
Bridge terminals 1 and 2 (not 3!) are red and green (or maybe green and red, depending on which lamps you put where) and go to the NO and NC (or NC and NO, depending on which light you want on when the train is present or absent) terminals of the relay. Bridge terminal 3 (not 2!) and the common terminal of the relay contacts go to the two terminals of your power supply, whatever it is.
Usually, this kind of signal is set up to be green until the train gets there, then to switch to red as the train passes it and to stay red until the train has gone.
Lionel mistakenly put the red lamp on top and the green lamp on the bottom, correct for traffic lights but backwards for railroad signals. You can of course put your lamps wherever you want, swapping the connections to terminals 1 and 2 to get them to work the way you want.
