When it may not be suitable

This relay is designed for standard electrical control circuits and may not be suitable for high-power direct load switching without an additional contactor. It is also not intended for applications requiring extreme environmental protection against water or dust ingress without an appropriate protective enclosure.

Key specifications

• Contact configuration: 1P (Single-pole)
• Time range: 1 second to 10 days
• Supply voltage: 12-240V AC/DC
• Frequency: 50/60 Hz
• Mounting: Standard DIN rail

How to use

To use the Relpol RPC-1SA-UNI, mount the device onto a standard DIN rail within your electrical cabinet. Connect the power supply to the designated input terminals, ensuring the voltage is within the specified 12-240V AC/DC range. Use the adjustment dials on the front panel to set the desired time delay according to your application needs. Once configured, connect your control circuit to the output terminals to initiate the delayed activation function.

What to consider before purchase

• Verify that the load current does not exceed the relay contact rating.
• Ensure the installation environment is free from excessive moisture and extreme temperatures.
• Confirm that the timing function matches your specific automation requirements.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring or adjustments to the relay to prevent electrical hazards. Periodically check the terminal connections to ensure they remain secure and free from oxidation.
