This description is intended solely as an illustration of how time delay relays function and is not intended to represent the operation of real-world traffic lights or any specific application. In this scenario, we are using time delay relays to create a controlled sequence of events: 1. TR1 (Time Delay Relay 1): • TR1 starts timing as soon as power is applied to the circuit. • When TR1 is energized, it also energizes CR1 (Control Relay 1). • CR1-1 closes, and since TR1-2 is initially closed, th
