How to set the operating mode on this device?

You can select the operating mode using the DIP switch settings provided on the timer relay.

What is the maximum current rating for the outputs?

The outputs can handle up to 3A at 250V AC for resistive loads.

Can it be used in locations with high ambient temperatures?

Yes, but ensure the supply voltage remains within 90% to 110% of the rated value if temperatures exceed 50°C.

Is it compatible with different voltage supplies?

It operates with 12V DC and can also function with 24V AC or V DC models.

What safety precautions should I take during installation?

Ensure no voltage is applied when setting the DIP switches, and avoid touching live terminals.
