Consumption AC supply DC supply Mode of Operation The relay operates and the time period starts when power supply is applied to the time relay. At the end of the set delay, the relay releases and will not operate again until power supply is reapplied. A recovery period of 250 ms should be allowed before reapplying power supply. If power supply is interrupted for more than 250 ms before the time period has expired, the relay releases and the time is reset to zero.
