Time Delay Off Relay FF PO-415 16A 230V — DIN-mount timing relay

FF PO-415 is a DIN-rail mount time delay off relay designed for delayed turn-off control of AC loads. Rated for 16A at 230V AC, this timing relay provides a configurable off-delay interval that maintains power to the load for a preset time after the control input is removed. The compact design suits electrical panels and distribution enclosures where a reliable, repeatable delayed shutdown is required for equipment such as motors, lighting circuits and HVAC components.

Advantages

The relay supports a 16A switching capacity at 230V AC, allowing it to handle moderate power loads reliably. Its DIN-rail form factor simplifies installation in standard control cabinets and reduces panel space. The off-delay timing function is adjustable to match process requirements, providing consistent delayed turn-off behavior in automation and building control applications. The device is intended for straightforward integration with typical control circuits and contactor arrangements.

Suitable for

• Delayed shut-off of motor starters and soft starters
• Sequenced switching of lighting groups and emergency lighting
• HVAC system components requiring timed de-energization
• Machinery and conveyor circuits that need post-run cooling or safety delays

Key specifications

• Mounting: DIN-rail compatible
• Rated switching current: 16 A at 230 V AC
• Function: off-delay timing relay (time delay off)
• Control input: standard AC control voltage (230 V AC)
• Typical applications: motor control, lighting, HVAC, industrial automation

How to use

Mount the relay on a standard DIN rail inside the control panel and make electrical connections according to the system’s wiring diagram, ensuring power is isolated during installation. Apply the control voltage to the relay’s input; when the control input is removed, the relay will keep the load energized for the preset off-delay interval before opening the output contacts. Adjust the off-delay setting per the equipment manufacturer’s recommendations or process requirements. Verify correct operation by performing functional tests with the connected load and observe timing behavior across expected operating conditions.

Usage recommendations

Ensure that the connected load does not exceed the rated 16A at 230V AC and use appropriate protection (fuses or circuit breakers). For inductive loads such as motors or contactors, include appropriate suppression or use auxiliary contact arrangements where needed. Always follow local electrical codes and safety standards when installing and configuring the relay.
