    Input Characteristics

    Maximum switching voltage (channel-to-channel and channel-to-ground)

    30 V

    Maximum switching current

    0.33 A

    Maximum carry current

    0.33 A

    Maximum switching power

    10 W

    spd-note-note
    Note  

    NI recommends against switching active RF signals. As a relay actuates, the channel is momentarily unterminated. Some RF sources can be damaged by reflections if their outputs are not properly terminated. Refer to your RF source documentation for more information.

    Maximum RF carry power

    1 A

    DC path resistance

    Initial

    <0.2 Ω

    End of life

    >1 Ω

    Path resistance is a combination of relay contact resistance and trace resistance. Contact resistance typically remains low for the life of a relay. At the end of relay life, the contact resistance rises rapidly above 1.0 Ω.
