Dual Traffic Light Controller

by Galak Electronics
Part No. VG-303
Shipping Weight: 1.0 ounce (28 grams)

Whether your adding traffic lights to your model railroad layout or looking for an educational kit, the Dual Traffic Light Controller is the perfect solution. Accepting either AC or DC power, this controller provides up to 500mA per channel and can be configured to drive LEDs or incandescent lamps. Includes screw terminal headers for easy connection.

The unassembled kit includes instructions (including schematic and parts placement) and all the components to build one complete Dual Traffic Light Controller. A soldering iron, solder and a pair of cutters are required for assembly.
