Time relay PCU-520 F&F
Product description
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 contacts remain in positions 1-5, 2-8. When the supply voltage is applied, the contacts are switched to positions 1-6, 2-7 for time t1. After time t1 has elapsed, the contacts return to positions 1-5, 2-8 for time t2. After time t2, the relay contacts return to position 1-5, 2-8 for time t2. After time t2, the relay contacts return to position 1-6, 2-7 The relay mode can be realized again after the power supply voltage is disconnected and switched on again.
*DELAYED SWITCHING ON (B)
After the supply voltage is applied, the contacts remain in position 1-5, 2-8 for time t1. After time t1 has elapsed, the contacts are switched to positions 1-6, 2-7 for time t2. After the time t2, the relay contacts return to the position 1-5, 2-8. Re-execution of the relay mode of operation is possible after disconnection of the supply voltage and switching it on again.
*DELAYED SHUTDOWN - CYCLIC (C)
The mode of operation of delayed deactivation realized cyclically at preset intervals of operation and interruption.
*DELAYED SWITCH-ON - CYCLIC (D)
The mode of operation of delayed switch-on realized cyclically in the set intervals of work and break.
Attention!
* When the power is on, the system does not react to a change in the time range settings.
* Operation with the newly set time range is carried out after the power supply is switched off and switched on again.
* When the power is switched on in the set time range, it is possible to smoothly adjust the time within the range of the time setting value.

ON - when power is on, causes permanent contact switching in positions 1-6 and 2-7.
OFF - when the power is on, it causes permanent switching of the contact in positions 1-5 and 2-8.
