6-Channel AC Traffic Light Controller

6-Channel AC Traffic Light Controller

by Galak Electronics
Part No. VG-307
Shipping Weight: 2.7 ounce (76 grams)

Newly released, the 6-Channel Traffic Light Controller will power all your traffic light needs. Accepting standard 120VAC line voltage, this controller provides up to 550 Watts per channel and will drive most full-sized traffic lights. Realistic features include flashing "don't walk" signal in crosswalk mode and two different arrow sequencing modes.

The unassembled kit includes instructions (including schematic and parts placement) and all the components to build one complete 6-Channel Traffic Light Controller. A soldering iron, solder and a pair of cutters are required for assembly.

6-Channel Traffic Light Controller Kit:



6-Channel Traffic Light Controller
(Built and Tested):




Mode 1:
Traffic Lights
Full Intersection







Mode 2:
Traffic Light
with Crosswalk







Mode 3:
Traffic Light
with Arrows
Sequence 1







Mode 4:
Traffic Light
with Arrows
Sequence 2








  • User selectable time delay from 20 seconds to 130 seconds (per RED or GREEN light).
  • Four modes (full interserction, traffic light with crosswalk, traffic light with arrows. See chart above.)
  • Separate digital control for "YELLOW" allowing for more realistic operation (4 to 7 seconds).
  • Wide input voltage range, accepting from 90 to 125VAC.
  • Independent outputs channels for operating LEDs or Incadescent lamps at the input voltage.
  • Solid state switching for silent operation (no clicking mechanical relays).
  • Snubbing circuitry to protect from inductive kickback and reverse voltage spikes.
  • Onboard LEDs to show current output states.
  • Compatible with virtually all types of 120VAC traffic lights.
