Time relay PCU-518 PCU-518DUO

Purpose
Relays  temporary   are used for  time control in industrial and home automation systems (e.g. ventilation, heating, lighting, signaling, etc.). Until the relay is switched on, the contact remains in position 11-10. After applying the supply voltage, the contact is switched to position 11-12  and the preset working time t is measured. After the time t has been measured, the contacts return to position 11-10. Reactivation of the relay's operating mode is possible after disconnecting the supply voltage and reconnecting it.
*OPÓDELAYED SWITCH ON (B)
Before and after applying the supply voltage, the contact remains in position 11-10 and the set time is measured t. After the time t has elapsed, the  contact in position 11-12. Re-execution of the relay operating mode is possible after disconnecting the supply voltage and switching it on again. intervals set  time and break.
*OPÓDELAYED SWITCHING ON - CYCLICALLY (D)
Delayed-on operation mode carried out cyclically in the same  intervals set  working time and breaks. Note!
* When the power supply is on, the system does not react to changing the time range settings.
* Operation with the newly set time range takes place after switching off and on again 
* When the power is turned on within the set time range, it is possible to smoothly adjust the time within the time setting value.                 ;             ON  - when the power supply is on, the contact is permanently switched on  in position 11-12.
 OFF  -  when the power is on, the contact is permanently switched on  in position 11-10.
