Function EWa
EWa - OFF delay and breaking time delay with opening of the control contact S. Independent settings of T1 and T2 intervals.
The input of the time relay is supplied with voltage U continuously. Closing of the control contact S switches on the output relay R. Opening of the control contact S starts the interval T1, and after the interval has lapsed, the output relay R switches off for the interval T2. Following the interval T2, the output relay R will be switched on again when the control contact S is closed on the lapse of the interval. In the course of the intervals T1 and T2 the position of the control contact S is of no importance.
Relays performing the function "EWa": MT-W..., RPC-1EA-...
