Ws - Single shot for the set interval triggered by closing of the control contact S.
The input of the time relay is supplied with voltage U continuously. Closing of the control contact S immediately switches the output relay R on for the set interval T. After the interval T has lapsed, the output relay R is switched off. In the course of the interval T, any opening of the control contact S does not affect the function to be performed. The output relay R may be switched on again for the set interval, after the interval T has lapsed, by closing the control contact S again.
Relays performing the function "Ws": MT-W..., RPC-.MA-..., RPC-1MC-UNI, RPC-.MD-UNI, TR4N 1CO, 2CO, TR4N 4CO, PIR15...T
