Time relay PCR-515 DUO, single-function - reverse (delayed switching on), contacts: 1P, U = 230 and 24V, I = 10A, 1 module PCR-515DUO

Time relays are used for time control in industrial and home automation systems (e.g. ventilation, heating, lighting, signaling, etc.).
Action
After the supply voltage is applied, the contact remains in position 11-10 and the countdown of the set operation time follows. After the time has elapsed, the contact switches to position 11-12. Re-implementation of the relay operation mode is possible after disconnecting the supply voltage and switching it on again.
