    About These SpecificationsSpecifications characterize the warranted performance of the instrument under the statedoperating conditions.

    Typical Specifications are specifications met by the majority of the instrument under the statedoperating conditions and are tested at 23 C ambient temperature. Typical specifications arenot warranted. The following specifications are typical at 23 C unless otherwise specified.

    All voltages are specified in DC, ACpk, or a combination unless otherwise specified.

  • Caution The protection provided by the NI 2503 can be impaired if it is used in amanner not described in this document.

    Input CharacteristicsAll input characteristics are DC, ACrms, or a combination, unless otherwise specified.

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

    30 VAC, 60 VDC

    Maximum switching current (per channel) 1 A

    Maximum carry current (per channel) 1 A

    Maximum switching power (per channel) 30 W

    Minimum switch load 10 A, 10 mV

    Caution The switching power is limited by the maximum switching current andthe maximum voltage. Switching power must not exceed 30 W (37.5 VA) perchannel.

    DC path resistance

    Initial 2

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

    Thermal EMF (differential) 100 dB

    100 kHz >80 dB

    1 MHz >55 dB

    10 MHz >30 dB
