PXI-2586 Specifications

    Last Modified: December 13, 2017


    The protection provided by the PXI-2586 can be impaired if it is used in a manner not described in this document.


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

    The following characteristic specifications 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 performance met by a majority of models.
    • Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.

    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.







    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.

    Maximum switching voltage[1]


    300 V


    300 V, CAT II

    Maximum switching power for AC systems (per channel)

    3 kVA (up to 60 Hz)


    The switching power is limited by the maximum switching current and the maximum voltage. For AC systems, switching power must not exceed 3 kVA. For maximum DC switching power, refer to the following figure.

    Figure 1. Maximum Switching Power for DC Loads (Per Channel)
    Maximum current (switching or carry, per channel or common)

    Ambient temperature ≤45 °C

    12 A

    Refer to the following figure for the maximum current (switching or carry, per channel or common) for ambient temperatures >45 °C.

    Figure 2. Maximum Current for Ambient Temperatures

    Simultaneous channels at maximum current


    DC path resistance


    ≤50 mΩ, warranted


    >100 mΩ

    DC path resistance typically remains low for the life of the relay. At the end of relay life, the path resistance rapidly rises above 100 mΩ. Load ratings apply to relays used within the specification before the end of relay life.

    Minimum switch load

    12 V

    100 mA

    Bandwidth (-3 dB, 50 Ω termination)

    ≥20 MHz, typical

    Crosstalk (50 Ω termination)

    10 kHz

    ≤-85 dB, typical

    100 kHz

    ≤-65 dB, typical

    1 MHz

    ≤-45 dB, typical

    10 MHz

    ≤-25 dB, typical

    Isolation (50 Ω termination)
    Open channel

    10 kHz

    ≥90 dB, typical

    100 kHz

    ≥70 dB, typical

    1 MHz

    ≥50 dB, typical

    10 MHz

    ≥30 dB, typical

    Module Load Derating


    A total power load greater than 400 A2 × channels will damage the PXI-2586 under certain conditions.

    Load derating is dependent on the sum of the current squared of each channel simultaneously carrying a signal. The result must be less than 400 A2 × channels. The following formula represents this calculation:

    N = 0 9 I 2 c h a n n e l N 400 A 2 × c h a n n e l s

    When operating at ambient temperatures >45 °C, refer to the derating chart in the preceding figure for the maximum allowed current per channel.

    Example 1: One channel carries 8 A while five channels carry 6 A.

    (1 × 82) + (5 × 62) = 244 A2 × channels

    The module represented in Example 1 is acceptable because the result of the calculation is less than 400 A2 × channels.

    Example 2: Five channels carry 5 A while four channels carry 9 A.

    (5 × 52) + (4 × 92) = 449 A2 × channels

    The module represented in Example 2 is not acceptable and will be damaged under certain conditions.

    15.4 ms, maximum

    • 1 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.
