    About These Specifications

    Specifications 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 and are tested at 23 °C ambient temperature. Typical specifications are not warranted.

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

    Input Characteristics

    Maximum switching voltage


    150 V


    150 V, CAT I[1]


    This module is rated for Measurement Category I and intended to carry signal voltages no greater than 150 V. This module can withstand up to 500 V impulse voltage. Do not use this module for connection to signals or for measurements within Categories II, III, or IV. Do not connect to MAINs supply circuits (for example, wall outlets) of 115 or 230 VAC.


    When hazardous voltages (>42.4 Vpk/60 VDC) are present on any relay terminal, safety low-voltage (<42.4 Vpk/60 VDC) cannot be connected to any other relay terminal.


    The maximum switching power is limited by the maximum switching current and the maximum voltage, and must not exceed 60 W.

    Maximum switching power (per channel)

    60 W


    This module and cable accessory can operate at various ambient temperatures and currents as shown in the following table.

    Table 1. NI PXI-2510 Operating Currents
    Current Module Alone Module with Cable
    Operating temperature range 0 to 55 °C 0 to 55 °C 0 to 40 °C
    Maximum total module current 64 A 32 A 48 A
    Maximum current per channel 2 A 1 A 1.5 A[2]

    Minimum switch load

    1 mA

    Maximum DC path resistance (channel-to-DUT)


    150 mΩ, typical


    >1 Ω


    DC path resistance typically remains low for the life of the relay. At the end of relay life, the path resistance rapidly rises above 1 Ω. Load ratings apply to relays used within the specification before the end of relay life.

    Bandwidth, typical (50 Ω system)

    .>6.5 MHz[3]

    Dynamic Characteristics

    Relay Operate Time[4]


    1 ms


    3 ms

    Expected mechanical relay life

    1×108 cycles

    Expected electrical relay life

    30 V, 1 A

    5×105 cycles

    30 V, 2 A

    1×105 cycles

    Simultaneous drive limit

    38 relays


    Relays are field replaceable. Refer to the NI Switches Help for more information about replacing a failed relay.


    Certain applications may require additional time for proper settling. Refer to the NI Switches Help for more information about including additional settling time.


    Opening a CHn to DUTn path counts toward the simultaneous drive limit.

    Trigger Characteristics

    Input trigger


    PXI trigger lines <0..7>

    Minimum pulse width

    150 ns


    The PXI-2510 can recognize trigger pulse widths less than 150 ns if you disable digital filtering. Refer to the NI Switches Help for information about disabling digital filtering.
