CONTROL OF TRAFFIC LIGHT WITH THREE COLOURS AND
HAZARD’S STATE USING PLC ZELIO SCHNEIDER ELECTRIC
This paper presents an application made to control of traffic lights with
three colors and hazard’s state simulated and implemented using ZelioSoft 2.
Also, program has been tested on laboratory bench comprising: a power source
model THF45US24, a PLC Telemecanique Zelio SR3 B261BD type with 24VDC
power supply, and Schenck simulation module with 2 analog inputs, 8 digital
inputs, and 8 relay outputs.
