8A NO/NC 230V AC / 24V AC/DC time relay PCU-511DUO F&F
Product description
Timing relays are used for time control in industrial and home automation systems (e.g.: ventilation, heating, lighting, signaling, etc.).
Operation
Time relays are used for time control in industrial and home automation systems (e.g.:ventilation, heating, lighting, signaling, etc.).
Operation
Functions:
*DELAYED SHUTDOWN (A)
Until the relay is switched on, the contact remains in position 11-10 (3-5 for PCU-511 UNI). When the supply voltage is applied, the contact is switched to position 11-12 (3-7 for PCU-511 UNI) and the set operation time t is measured. After the time t is measured, the contact returns to position 11-10 (3-5 for PCU-511 UNI). Re-execution of the relay operation mode is possible after disconnecting the power supply voltage and switching it on again.
*DELAYED ACTIVATION (B)
Before and after the supply voltage is applied, the contact remains in position 11-10 (3-5 for PCU-511 UNI) and the set operation time t is measured. After the time t is measured, the contact switches to position 11-12 (3-7 for PCU-511 UNI). Re-execution of the relay operation mode is possible after the power supply voltage is disconnected and switched on again.
*DELAYED DEACTIVATION - CYCLIC (C)
The operation mode of delayed deactivation realized cyclically at equal intervals of the set operation time and interval.
*DELAYED SWITCH-ON - CYCLIC (D)
The mode of operation of delayed switch-on realized cyclically at equal intervals of the set operating time and interval.
Attention!
* When the power is on, the system does not react to the change of the time range settings.
* Operation with the newly set time range is carried out after the power supply is switched off and on again.
* When the power is turned on, smooth adjustment of the time within the set time range is possible.

oN - when power is on, causes permanent contact switching in position 11-12.
oFF - when the power is on, it causes permanent switching of the contact in position 11-10.
