In most IAC or CO relays, is the target/seal in coil in series with the time element coil?

In many IAC (Inductive Adjustable Control) and CO (Contact Operated) relays, the target or seal-in coil is typically not in series with the time element coil. The target/seal-in coil is usually designed to function independently of the time element coil to ensure proper operation and control of the relay's functionality without directly affecting the delay timing of the time element.

By maintaining these coils separate, it allows for more flexible control and operation, as the target function can maintain the relay's state once energized, while the time element operates based on its specific delay settings. This design supports efficient relay operation and minimizes potential conflicts between the two functions.

Options suggesting that this relationship changes based on model, manufacturer, or specific circumstances could mislead, as the general operational principle in relays will often keep these coils operating independently for reliability and accuracy. Thus, stating that it is false that these coils are in series aligns with the typical design and functionality of these relays.
