Single cycle time relay and double cycle time relay What is the difference
Double cycle time relay can set two times, the first step: the first time to time after the relay action and keep the second step: the second time to start the time, the second time to time after the relay to restore the original state , And then back to the first step to repeat the above two steps, continuous cycle, is a double cycle.
You say that the single cycle time relay can only set a time, after the start of the timer, the time after the relay relay action and maintain the state after the action; if you want to restore the original state must be reset or disconnect the power plus power.
1 and 2 time relay, the number is not the same
