Question:

Time relay time to complete, is to maintain the final state or start timing?

Time relay time to complete, is to maintain the final state or start timing? The There is a time relay a power, often open contact on the closed, or timing is completed before closing?

Answer:

Time relay time to complete, to maintain the final state can be. Time Relay: Time relay refers to a relay that produces a jumping change (or contact action) when the output circuit is subjected to a predetermined exact time after adding (or removing) the input action signal. Is an electrical component that is used to circuit on a lower voltage or a smaller current that is used to turn on or off a circuit with a higher voltage and a larger current. At the same time, the time relay is also a use of electromagnetic principle or mechanical principle to achieve delay control of electrical control. It is a lot of type, with air damping type, electric type and electronic type.

Time relay is in the state of power to complete the time, after the completion of the delay as long as the loss of power, the time relay always maintain the final state, restart the time must be power, and then power; Time relay a power, delay start, when the time to complete the normally open contact was closed, normally closed contact off. Or not called the delay on the off. hope this helps

Application in the circuit, depending on power delay, or power delay. Such as power delay: power, the time relay coil power, to set the time, normally open and close, normally closed off, if the line is broken, back to the original state. Such as power-off delay: power failure, the time relay coil power failure, to set the time, often open open, normally closed closed.
