Time relay PO-415 with delayed dropout, contacts: 1P, U=24V, I=10A, 1 module PO-415-24V

Time relay PO-415 is a reliable device for installations requiring sustained power to the receiver after the control voltage is lost. It is particularly useful in bathroom ventilation systems, ensuring the fan continues to operate after the light is switched off. Thanks to its delayed dropout function, it allows for smooth and comfortable operation of home and industrial automation systems.

The device features a compact design – it occupies only 1 module, making it easy to mount in distribution boards. Made of high-quality materials, it ensures long-lasting and trouble-free operation. The PO-415 relay is powered by 24V AC/DC and has contacts with a capacity of 10A, allowing control of various receivers. Connection is made using convenient screw terminals.

Functionality and application

The time relay with delayed dropout works as follows: after applying the control voltage, the relay switches on the receiver circuit. After the control voltage is lost, the receiver remains powered for the set time (in the range of 1-15 seconds) and is then automatically switched off. If the control voltage is reapplied before this time elapses, the cycle restarts. This characteristic makes it ideal for applications requiring short-term power maintenance after the control signal is lost.

Construction features and mounting

The device is designed for mounting on a 35 mm rail (although there is no information about mounting on a TH rail in the technical data), which greatly simplifies installation and servicing. The operating status is indicated by LEDs – red (contact status) and green (power supply). Compact dimensions (18 mm wide, 90 mm high and 65 mm deep) allow installation even in limited space. Electrical connections are made using screw connections, accepting wires with a cross-section of up to 2.5 mm².
