The relay can generate the minimum current for pull-in operation. In normal use, the given current must be slightly larger than the pull-in current, so that the relay can work stably. As for the coil plus the operating voltage, generally not more than 1.5 times the rated operating voltage, otherwise it will have a larger current and the coil burned.

As a control element, in summary, the relay has the following functions:

1) Expand the scope of control. For example, multi-contact relay control signal reaches a certain value, you can contact the different forms of contacts, while switching, breaking, connected to multiple circuits.

2) Zoom in. For example, sensitive relays, intermediate relays, etc., with a very small amount of control, you can control the very high power circuit.

3) Synthesis signal. For example, when a plurality of control signals are input to the multi-winding relay in the prescribed form, after the comparison, the predetermined control effect is achieved.

4) Automatic, remote control, monitoring. For example, relays on automation devices, along with other appliances, can form a program control circuit for automated operation.
