Time Relay FF PO-415 24V, delayed off, 16A — industrial control timer

FF PO-415 24V is a time relay with a delayed-off (timed turn-off) function designed for industrial control and automation circuits. The device accepts a 24 V supply and controls loads up to 16 A, providing reliable timed interruption of power to motors, lamps, solenoid valves and control modules. The compact relay offers adjustable delay intervals and repeatable operation for sequences where a defined off-delay is required.

Advantages

The time relay provides accurate and stable delayed-off timing and supports switching of resistive and inductive loads up to 16 A. Its 24 V supply compatibility makes it suitable for common control systems and PLC interfaces. The relay is designed for easy panel or rail mounting and offers consistent repeatability and long service life suitable for continuous industrial operation.

Suitable for

• Delayed shutdown of electric motors and pumps
• Control of lighting circuits requiring timed turn-off
• Solenoid valve de-energizing in pneumatic or hydraulic systems
• Sequencing and interlocking in control panels and automation racks

Key specifications

• Supply voltage: 24 V DC
• Function: delayed-off (off-delay) timing
• Maximum switching current: 16 A
• Contact type: single-channel power switching suitable for resistive and inductive loads
• Adjustable delay range: user-adjustable timing interval (factory and user settings available on the unit)
• Mounting: panel or DIN rail compatible housing for electrical control cabinets

How to use

Install the relay into the control panel or on a DIN rail and connect the 24 V supply to the designated supply terminals. Wire the load to the relay's output contact following the circuit diagram on the device. Set the desired off-delay using the front-panel adjustment or selector, then apply control input to trigger the timing cycle. When the control signal is removed, the relay will keep the output energized for the selected delay interval and then switch off automatically. Verify wiring and perform initial functional tests before placing the relay into continuous service.

Usage recommendations

Select wiring that meets local electrical codes and use appropriate fuses or circuit breakers sized for the connected load. For inductive loads such as motors and solenoids, consider using suppression components or contact protection to increase contact life. Periodically inspect terminals for tightness and signs of wear, and ensure ambient conditions remain within the relay's rated operating temperature for stable timing performance.
