Why is the relay marked two modes ah, one is the main contact rated voltage 5A AC 240V The other is the main contact rated voltage 5A DC 28V.
Why is the relay marked two modes ah, one is the main contact rated voltage 5A AC 240V and the other is the main contact rated voltage 5A DC 28V. Then I connected to the main contact 3A AC120V or 1A DC 24V can
Exchange and DC two ah, not the same, as long as the range is in line with the installation requirements
Contact with rated voltage and rated current value, you can not be connected to the rated value. Small points can be used. The two modes are because the requirements are different, one is the exchange of a DC.
The meaning of the label is the contact capacity of the resistive load maximum AC voltage of 240V 5A. Or resistive load the maximum DC voltage of 28V. 5A. You have to use no contact capacity, you can use.
