Time relay with delayed dropout, DIN rail mounting, 230V with delayed dropout, time range 1÷15min, Un=230V~, Io<16A, mounting on TH-35 rail PO-415

Time-delay relay – reliable lighting and ventilation control

The PO-415 time relay is a device designed for mounting on a TH-35 rail, ideal for applications requiring sustained power to the receiver after the control voltage is lost. Particularly useful in bathroom ventilation systems, where it ensures the fan continues to operate after the light is switched off. This effectively removes moisture and maintains a high level of comfort in the bathroom.

Functionality and application

The device is characterized by a time-delay dropout, which means that after the control voltage is lost, the receiver remains powered for a set time. This time can be adjusted from 1 to 15 minutes, allowing the relay's operation to be tailored to specific application needs. The PO-415 relay is used not only in bathroom ventilation but also in other home and industrial automation systems where delayed shutdown of the load is required.

• Bathroom ventilation: Maintaining fan operation after the light is switched off for effective moisture removal.
• Lighting: Delayed shutdown of lighting in utility rooms or corridors.
• Home automation: Integration with smart home systems to control various devices.
• Industrial applications: Controlling the short-term operation of devices after the control signal is lost.

Technical specifications and installation

The PO-415 relay has been designed for easy installation and reliable operation. Mounting is done on a standard TH-35 rail, ensuring stability and safety. Electrical connection is made using screw terminals, accepting wires with a cross-section of up to 2.5 mm². The supply voltage is 230V AC, and the maximum load current is 10A. Built-in LEDs indicate the on state (green) and contact state (red), making diagnosis and device operation control easier.

The device characteristics include a supply voltage of 230V AC and an adjustable time range from 1 to 15 minutes. The maximum load current is 10A, and the connection is made using screw terminals adapted for wires with a cross-section of up to 2.5 mm². The relay is mounted on a TH-35 rail. The on state is indicated by a green LED, and the contact state – by a red LED. The device is 1 module wide (18 mm).
