What other component is often used in combination with isolators in traffic signal systems?

In traffic signal systems, detectors are integral components often used alongside isolators. Detectors serve to sense the presence of vehicles or pedestrians at intersections, triggering appropriate responses from the traffic signal system. When isolators are used to prevent electrical interference and ensure the reliability of the signal circuit, detectors complement this function by dynamically adjusting signal timing and operations based on real-time traffic conditions. This synergy allows for improved traffic flow and safety, as the system can respond promptly to changing traffic patterns.

While transformers, timers, and relay systems play important roles in traffic signal functionality, they do not have the same direct interaction with isolators in the context of detecting vehicle presence and controlling signal operations. Detectors provide critical input that allows the entire system, including isolators, to function more effectively in real-time traffic management.
