My initial thought with the controller was to connect the outputs each to a relay. I could then use the relay contacts to control as many lights and intersections as I wanted.

Unfortunately, there doesn't appear to be any relays that will operate on the 1.5 volt output of the controller's terminals. It could probably be configured as a low level input to an external low input/high output circuit, but I never got that far with it.

I first put the lights in over three years ago so I've long misplaced the instructions but at the time I put them in I was having some problems so I called the tech services people at Walthers and they told me that each controller would handle four lights (two intersections) so when I hooked them up that way (after I bought another controller) they sequenced properly at both intersections.  I have two single sided lights at each intersection for a total of eight lights and two controllers. ( I thought at the time that the capacity of the controller was designed to sell more controllers.).  I have not tried putting four lights at each intersection but that might work.  The problem I had using one controller for three intersections was that the lights would not sequence correctly for the traffic flow.

I think the specification says it will handle "two intersections."  I assume that means eight light faces.  "Two Circuits" means one set for the North-South facing lights, and the other for the East-West facing lights.

I use mine to drive 2 intersections, but only 3 light faces at each.  I'm going to add a third intersection, which will push the limit.  But, the lights themselves are LEDs so I hope I'll get away with it.

You can hook up four lights to each controller - each controller has two circuits so I put two lights on each circuit.

Curious - How many of the traffic lights are you able to run off of one controller ? I have a controller, but have yet to get it hooked up to anything.

Go to Home Depot. Wal-mart, Sears, Lowe's, or other big box store that sells door bell components and get a door bell transformer.  Most of them have an output in the range of 16 VAC and they are designed to be always on.

Walthers Traffic Light controller
Posted by dadret on Tuesday, April 24, 2012 9:12 AM

I've got several Walthers traffic lights hooked up to their Traffic Light Controller which requires a 19 VAC input (accessory terminals on a power pack) and that's how I have it hooked up.  I'm redoing my layout and would like to connect the controllers to some kind of wall transformer or power supply just to simplify the layout and make the traffic light hookup similar to my other lights (street lights etc) but the closest thing I can find is a 24 VAC power supply.  Is there anything else available to make this hookup?
