Time relay FF PO-406 with delayed off function, 230 V AC, 10 A

FF PO-406 is a time relay with a delayed-off (falling) function designed for control and automation circuits. Rated for 230 V AC supply and switching currents up to 10 A, this relay provides a timed disconnection of loads to ensure predictable turn-off behavior in lighting, motor control, heating circuits and other electrical systems. The compact module fits standard control panels and DIN-rail assemblies used in residential and light industrial installations.

Advantages

The FF time relay offers a reliable delayed-off function that keeps the load energized for a preset interval after the control signal is removed, reducing wear from frequent switching. Its 230 V AC compatibility and 10 A switching capacity cover common single-phase loads without the need for additional contactors in many applications. The device’s straightforward electrical characteristics and compact form make it easy to integrate into existing control circuits while maintaining stable timing performance.

Suitable for

• Timed lighting turn-off in corridors, stairwells and exterior lighting
• Delay-off control for small motors and fans
• Heating element control where delayed disconnection is required
• Automation circuits in residential and commercial control panels

Key specifications

• Supply voltage: 230 V AC
• Function: delayed off (falling) timing
• Maximum switching current: 10 A
• Mounting: panel or DIN-rail compatible compact module
• Intended use: control and automation circuits for resistive and inductive loads within rated current

How to use

Install the relay in the control panel according to the wiring diagram provided with the device, connecting the supply to the 230 V AC terminals and the controlled load to the switched output. Set the required off-delay time using the timing control (or selector) on the module if applicable. After commissioning, the relay will energize the output while the control input is present and start the delayed-off countdown when the input is removed, opening the output after the set interval.

Usage recommendations

Ensure the connected load does not exceed the 10 A rating and account for inrush current of motors or lamps. Use appropriate overcurrent protection and follow local electrical codes when installing. For inductive loads or higher currents, consider using the relay to drive a suitably rated contactor. Verify wiring and timing settings during initial testing before putting the circuit into regular operation.
