    This document lists specifications for the NI PXI-2503 multiplexer/matrix module. All specifications are subject to change without notice. Visit ni.com/manuals for the most current specifications.

    Topologies ...................................... 1-wire 48 1 multiplexer,2-wire 24 1 multiplexer,2-wire Dual 12 1 multiplexers,2-wire Quad 6 1 multiplexers,4-wire 12 1 multiplexer,2-wire 4 6 matrix

    Refer to the NI Switches Help for detailed topology information.

    Caution To ensure the specified EMC performance, operate this product only with shielded cables and accessories.

    Caution Refer to the Read Me First: Safety and Electromagnetic Compatibility document at ni.com/manuals for important safety and compliance information.

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

    Typical Specifications are specifications met by the majority of the instrument under the stated operating conditions. The performance of the instrument is not warranted. Typical specifications are tested at 23 C.

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

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

    Maximum switching voltage ...........30 VAC, 60 VDC(channel-to-channel and channel-to-ground)

    Maximum switching current ...........1 A(per channel)

    Maximum carry current...................1 A(per channel)

    Maximum switching power.............30 W(per channel)

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

    DC path resistance

    Initial ...........................................2

    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 rapidly rises above 1.0 .

    Thermal EMF (differential).............
