Time relay PCU-504 UNI F&F
Product description
Time relay is used for time control in industrial and home automation systems (such as ventilation, heating, lighting, signaling, etc.).
The relay has a hold function of up to 10 minutes and contact switching after a power supply failure.
Operation
Functions:
A-SUSTAIN
When the relay is energized, the contacts are switched on (position 5-4/8-7). After the power supply voltage is lost, the contact switching is maintained for the preset time. After the set time the contacts will be disconnected (position 5-6/8-9).
B-DELAYED SWITCHING ON
After the supply voltage is applied the contacts remain open (position 5-6/8-9) for the set time. After the time elapses, the contacts are switched on (position 5-4/8-7) until the supply voltage is lost.
C-DELAYED CLOSING WITH HOLDING
After the supply voltage is applied, the contacts remain open (position 5-6/8-9) for the set time. After the time has elapsed, the contacts are switched on (position 5-4/8-7). After the supply voltage is lost, the contacts are kept on for the set time. After the set time the contacts will be disconnected (position 5-6/8-9).
Attention!
* When the power is on, the system does not react to the change of time and function settings.
* Operation with new function and time settings occurs after the power supply is switched off and switched on again.
