Question:

Loss of power delay time relay, power delay time relay, respectively, how the role, please point

Loss of power delay time relay, power delay time relay, respectively, how the role, please point

Answer:

Power loss delay time relay: When the time relay is energized, the normally closed delay contact immediately becomes open, and the normally open delay contact real-time turns on; when the time relay is de-energized, it starts to reset to the set time reset ( Often open the original state). Power delay time relay: When the time relay is energized, it will turn on. When the time relay is turned off, it will return to normal time. Original state).

Regardless of the principle of the results: Power loss delay is the relay in the connected voltage after the normal work, such as normally open point closed normally closed point off, after losing the coil power, delay, return to the initial state, that is, after the closure of the normally open point After a period of time to disconnect, and the closure of the closed point to be separated after a period of time to close.

The delay is that the relay is delayed after the relay is turned on to work, such as normally open point after a period of time to close, normally closed at a period of time before the break, and power quickly after the return to the initial state.
