Timing relays PCU-504 UNI
PCU-504UNI, 5908312598503
Product description
The time relay is used for time controlling in industrial and home automation systems (e.g. ventilation, heating, lighting, signalling, etc.).Time relay with backup after power failure.
The relay can maintain power for up to 10 minutes and switch the contact position after power failure.
Functioning
Features:
A - MAINTAINING
Powering up of the relay is followed by the closing of the contacts (position 5-4/8-7). After power failure, the contact position is maintained for a set period of time. When the specified time is up, the contacts open (position 5-8/8-9).
B - DELAYED ACTIVATION
When the power voltage is switched on, contacts remain open (position 5-6/8-9) for the preset time. After that time contacts close (position 5-4/8-7) until power is off.
C - DELAYED ACTIVATION WITH MAINTAINING
When the power voltage is switched on, contacts remain open (position 5-6/8-9) for the preset time. After that time contacts close (position 5-4/8-7). After de-powering contact remain closed for a preset time. When the specified time is up, the contacts open (position 5-6/8-9).
Note!
* When the power is on, the system does not respond to changes in the setting of time and function.
* The new settings of functions and time are operation after power restart.
