Time relay with power-off support 1NO/NC 12-264V - PCU-504

Intended use: The time relay is used to control the time in industrial and home automation systems (e.g., ventilation, heating, lighting, signaling, etc.) and change the contact after a power outage.

Operating functions:

• A-MAINTAIN: After the relay power is turned on, the contacts are activated (position 5-4/8-7). After a power outage, the contacts remain activated for the set time. After the set time, the contacts will disconnect (position 5-6/8-9).
• B-DELAY 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 activated (position 5-4/8-7) until the supply voltage disappears.

Note: When the power is on, the system does not respond to changes in time and operation settings. Operation with new function and time settings is performed after the device is turned off and on again.

Technical specifications:

• Power supply: 12÷264V AC/DC
• Charging current AC-1: 2×4A
• 2P split contact
• Time setting: Function A and C 0.1s÷10min.
• Function B: 0.5s÷16min.30s delay on for preventive operations.
