Traffic Light Controller

[2Biz]

For us Tri-Foam users, a cheap part to have on the shelf - Just in case -

Seller says they have them running traffic lights 24-7 for at least 6 years. I doubt we would ever put that many cycles on it. Cheap ($34.99) alternative to the pricy ones offered to us from the CW Industry. Also offered in 24vac. and other voltages.

No comments?! You guys like paying up to $300 or more for a TF sequencer?

I pay $140 for a ladder relay, and I program it for each color to overlap for 10 seconds so I get red, orange, yellow, green, blue, purple, red, etc. instead of just three colors.

I could do the same with a PLC, but that's costly to have on the shelf waiting......If your PLC goes belly up, what do you do? Just thought a $35.00 part that does Exactly the same thing as a TF sequencer is well worth having on the shelf for that day when all hell breaks loose...Its not if, its when!

If you're building a new system, there ya go....A Cheap sequencer that has enough life cycles if you used them up, you'd be a millionaire!

I have yet to have a Siemens ladder relay fail, other than at one wash where the guy knew he had lightning problems and instead of dealing with it properly replaced his blown fuses with brass tubing splicers because he was tired of paying $5 a fuse.

I'd probably use something like that sequencer to replace a GinSan controller. Now I'm curious what that cheap Kleen-Rite system uses.
