The TL-1 provides the timing circuitry to accurately reproduce the standard US style four step traffic light sequence. The outputs will drive LED or incandescent lamp signals (not included). If LED signals are used, they must be common anode (+) design. All four time periods are individually adjustable. The TL-1 is constructed on a 3” square printed circuit board and requires a 10-18 volt AC or DC input. Standard red, yellow and green outputs are provided for each direction (6 total) and each can drive a 250 ma. maximum load. Companion signals are manufactured by Busch and others. The TL-1 will directly replace the Busch European sequence flasher.
