Esa(R) - ON and OFF delay controlled with on and off of the S contact with the Reset function.
The input of the time relay is supplied with voltage U continuously. Closing of the control contact S begins the measurement of the set interval T - ON delay of the output relay R. If the control contact S is opened during the measurement of the interval T - ON delay of the output relay R, the measured time will be reset. The interval T measurement will start after the control contact S has been closed. After the set interval T has lapsed, the output relay R switches on. Opening of the control contact S will again trigger measurement of the set interval T - OFF delay of the output relay R, and after the interval has been measured, the output relay R switches off. If the control contact S is closed during the interval T measurement, the measured time will be reset. Opening of the control contact S will again trigger measurement of the interval T.
U - supply voltage; R - output state of the relay; S - control contact state; T - measured time; t - time axis
