WSK-20

Single shot timer (leading edge) with 2 C/O.
Control contact is required to perform this function, Supply connection between (A1) and (A2) must be continuous. On closure of the control contact between (A1) and (B1) the relay will energize and time out period starts to run, on completion of the time out period the relay will de-energize.

Activation of the control contact during the time out period has no effect. The relay drops out and timer resets automatically if the supply voltage is removed.
