PXI-2584 Specifications

    Last Modified: April 19, 2017

    This document lists specifications for the PXI-2584. All specifications are subject to change without notice.


    Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

    Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

    • Typical specifications describe the expected performance met by a majority of the models.
    • Nominal specifications describe parameters and attributes that may be useful in operation.

    Specifications are Typical unless otherwise noted.


    Specifications are valid at 23 °C unless otherwise noted.

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


    The protection provided by the PXI-2584 can be impaired if it is used in a manner not described in this document.



    1-wire 12 × 1 multiplexer

    1-wire dual 6 × 1 multiplexers

    2-wire 6 × 1 multiplexer

    2-wire 11 × 1 interleaved multiplexer


    Input Characteristics


    The PXI-2584 is not EMC protected and may generate emissions interference or disturbance. Relay contact actuation can cause unwanted emission disturbance in which case the installer or user will be required to take suppression measures such as, shielded cables, metal conduits, grounding, filtering, and protection techniques necessary to mitigate the source of interference or disturbance. The PXI-2584 is intended for use in industrial installations in which the user provides EMC controls.


    When hazardous voltages (>42.4 Vpk/60 V DC) are present on any channel, safety low-voltage (≤42.4 Vpk/60 V DC) cannot be connected to any other channel.


    This module is rated for 300 V Category II and 600 V Category I. This module can withstand up to 2,500 V impulse voltage. Do not use this module for connection to signals or for measurements within Categories III or IV. Do not connect this module to MAINs Category II circuits when operated above 300 V.

    Maximum switching voltage


    300 V, Measurement Category II

    600 V DC, V ACpk, Measurement Category I[1]


    300 V


    The switching power is limited by the maximum switching current and the maximum voltage. Switching power must not exceed 10 W.

    Maximum switching power (per channel)

    DC systems

    10 W

    Maximum current (switching or carry, per channel or common)

    0.5 A


    Switching inductive loads (for example, motors and solenoids) can produce high voltage transients in excess of the module’s rated voltage. Without additional protection, these transients can interfere with module operation and impact relay life. For more information about transient suppression, visit and enter the Info Code relayflyback.

    DC path resistance (1-wire path)


    ≤1.1 Ω


    >2 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 2 Ω. Load ratings apply to relays used within the specification before the end of relay life.

    Minimum switching capacity

    0.5 V

    1 mA

    Bandwidth (-3 dB, 50 Ω termination)

    ≥900 kHz, typical

    Isolation (50 Ω termination)
    Open channel

    10 kHz

    >86 dB, typical

    100 kHz

    >76 dB, typical

    1 MHz

    >58 dB, typical

    DC open channel isolation

    >1.0 × 1011 Ω, typical

    Thermal EMF (1-wire path, channel-to-common)

    <50 μV, typical

    Dynamic Characteristics

    Relay operate time

    0.4 ms, typical

    0.81 ms, maximum


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

    Maximum scan rate

    600 channels/s

    Expected relay life

    1 V at 10 mA resistive

    3 × 108 cycles


    600 V at 7 mA 90 pF capacitive

    1.8 × 107 cycles

    600 V at 16.5 mA 90 pF capacitive

    7 × 106 cycles


    Reed relays are highly susceptible to damage from in-rush currents. Switching capacitive loads without resistive or inductive protection can weld the relay contacts in less than 5 × 10 5 cycles.


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

    Trigger Characteristics

    Input trigger


    PXI trigger lines <0...7>

    Minimum pulse width

    150 ns


    The PXI-2584 can recognize trigger pulse widths less than 150 ns if you disable digital filtering. Refer to the NI Switches Help at for information about disabling digital filtering.

    Output trigger


    PXI trigger lines <0...7>

    Pulse width

    Programmable (1 µs to 62 µs)
