Has anyone designed an interface to use signs like TSS in bay message sign, and others to work with the g5 and laser 360? PDQ uses a pulse to ground to turn on the LED's on their signs, and i cant figure out how to hook up a relay to run the 120V.
If you are trying to get 120 V lights to come on with a chemical service you could use the chemical valve coil, they are all 24v ac. The outputs on the PDQ nodes can handle 2 amps, so adding a small ice cube relay is not an issue.
what I am looking for, is to be able to turn on a sectional sign with the outputs that are used to turn on the led's on the confirmation sign, but those are pulled to ground, and pulsed to fire the led lights. I'm thinking that there must be a way to do it, it just may take an electrical engineer to figure it out.
