PXIe-2512 Specifications
Topology | Independent |
Refer to the NI Switches Help for detailed topology information.
About These Specifications
Specifications characterize the warranted performance of the instrument under the following operating conditions:
- The PXI/PXIe chassis fan speed is set to High.
- The fan filters are clean.
- The empty slots contain filler panels.
For more information, refer to the Maintain Forced-Air Cooling Note to Users document available at ni.com/manuals.
Typical specifications are specifications met by the majority of the instruments under the stated operating conditions. Typical specifications are not warranted.
Data provided in this document are specifications unless otherwise noted.
Input[1]
All input specifications are DC, ACrms, or a combination unless otherwise specified.
Use the following equation to determine the maximum possible pulse width (seconds) for a given maximum inrush current “peak” amplitude (A) and steady state current (A).
DC path resistance | 16 mΩ, typical 35 mΩ, maximum |
Bandwidth (50 Ω system) | >800 kHz, typical |
Overcurrent Detection[4]
Overcurrent detection limit | 10.5 A typical |
Overcurrent detection delay | 20 ms |
Overtemperature Detection[5][6]
To help protect against fault conditions, the PXIe-2512 incorporates circuitry to detect overtemperature conditions.
The Switching Current Waveform graph figure indicates where on the inrush waveform you can find the parameters necessary for determining maximum cycle rate.
Determining the Maximum Cycle Rate
- Using the Maximum Cycle Rate figure, choose the plot line that meets or exceeds the peak inrush current value of the signal being switched. Find the point on the trace that equates to the steady state current being switched by the load.
- Find the corresponding intersection on the y-axis that indicates the maximum cycle rate allowed for a signal with a 50 μs maximum inrush pulse duration.
-
Find the point in the Maximum Cycle Rate Derating Factor by Pulse Width figure that corresponds to the measured pulse width of the inrush current pulse. Find the corresponding derating factor.
Then calculate the maximum cycle rate using the following equation:
where CR50 μs is the maximum cycle rate for a 50 μs wide inrush current pulse in Hz, and DF is the derating factor.
Note If the peak impulse current does not exceed 10 A, do not derate the maximum cycle rate below 220 Hz.
For switching a steady state current of 4 A into a load with peak inrush current of 45 A that lasts for 400 μs, choose the 50 A plot line in the Maximum Cycle Rate figure. Find the y-axis value that corresponds to the 4 A load current (650 Hz). Then find the derating factor in the Maximum Cycle Rate Derating Factor by Pulse Width figure that corresponds to 400 μs, which is 0.1.
The maximum cycle rate at which this signal can be switched by the module is calculated as follows:

1 Signal connections through the PXIe-2512 are intended to go through the DUTn pin connections. Signal paths that do not use the DUTn pin connections may exceed the module’s thermal capabilities.
2 Measurement Categories CAT I and CAT O (Other) are equivalent. These test and measurement circuits are not intended for direct connection to the MAINs building installations of Measurement Categories CAT II, CAT III, or CAT IV.
3 The maximum switching power is limited by the maximum switching current and the maximum voltage, and must not exceed 500 W.
4 After a switch operation, an overcurrent error condition occurs when both the overcurrent limit of the module is exceeded, and the overcurrent delay time has expired.
5 Exceeding the module’s thermal limit induces an overtemperature condition.
6 Overtemperature conditions are created when excessive power is dissipated in the channel paths such as when switching large impulses created by switching into capacitive or inductive loads or when switching a signal at a higher rate than the module dissipates the generated heat. Refer to the figures below for information about the maximum cycle rate.
7 Certain applications may require additional time for proper settling. Refer to the NI Switches Help for more information about including additional settling time.
8 The PXIe-2512 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.
