This traffic light control circuit is a great example of how sequential logic can be implemented using basic electrical components. Here’s a more detailed breakdown of the components and their functions in the circuit, as well as some additional insights:
▎Main Components:
1. S1, S2 (Push Buttons):
• S1: Start button to initiate the traffic light sequence.
• S2: Stop button to halt the operation of the circuit.
2. Q1 (Circuit Breaker):
• Provides overcurrent protection to prevent damage to the circuit in case of a fault.
3. K1, K2, K3 (Contactors):
• K1: Controls the green light (X1).
• K2: Controls the yellow light (X2).
• K3: Controls the red light (X3).
4. T1, T2, T3 (Time Delay Relays):
• Each timer is set to 3 seconds, controlling how long each light stays on before switching to the next one.
5. X1, X2, X3 (Indicator Lamps):
• X1: Green lamp indicating go.
• X2: Yellow lamp indicating caution.
• X3: Red lamp indicating stop.
