Esa -ON and OFF delay with the control contact S.
The input of the time relay is supplied with voltage U continuously. Closing of the control contact S starts the interval T- on-delay of the output relay R. After the interval T has lapsed, the output relay R switches on. Opening of the control contact S begins further measurement of the interval T - off-delay of the output relay R, and after the interval has lapsed, the output relay switches off In case the time for which the control contact S is closed in the course of measurement of the on-delay of the output relay R is shorter than the set interval T, the output relay R will switch on after the set interval T, and the output relay R will remain in on position for the interval T. When the output relay R is in on position, closing of the control contact S does not affect the function to be performed.
Relays performing the function "Esa": RPC-.MA-..., RPC-.MD-UNI, TR4N 1CO, 2CO, TR4N 4CO
