Input Characteristics

All input characteristics are DC, AC_rms, or a combination unless otherwise specified.

Maximum switching voltage

28 VDC, 19.8 V AC_rms, CAT I^[3]³ 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.

Caution Steady state voltages applied to the NI 2514 between any two I/O connector pins in excess of the maximum switching voltage specification may damage this module.

Caution This module is rated for Measurement Category I and intended to carry signal voltages no greater than19.8 V_rms/28 V_pk/28 VDC. 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.

Note Signal connections through the PXIe-2514 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. Refer to the connector pinout in the Diagrams section of this document for DUTn pin connections.

Maximum continuous current (per channel or common, switching or carry)
Single path closed	40 A
Multiple paths closed	25 A

Maximum pulsed current

200 A (for 1100 μs max)

Caution The maximum switching power is limited by the maximum switching current and the maximum voltage, and must not exceed 1,120 W.

Maximum switching power (per channel)

1,120 W

Use the following equation to determine the Maximum Possible Pulse Width (seconds) for a given Maximum Inrush Current “peak” amplitude (Amps) and Steady State Current (Amps).

MaxPulseWidth = \frac{45.5 - 0.02 \cdot (I_{SteadyState})^{2}}{(I_{PeakInrush})^{2}}

DC path resistance
Typical	5.5 mΩ
Maximum	10 mΩ

Typical bandwidth (50 Ω system)

>800 kHz

Overcurrent Detection

Note

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.

Overcurrent detection limit	41 A typical
Overcurrent detection delay	20 ms

Overtemperature Detection

To help protect against fault conditions, the PXIe-2514 incorporates circuitry to detect overtemperature conditions.

Note Exceeding the module’s thermal limit induces an overtemperature condition.

Note 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.

The Switching Current Waveform graph indicates where on the inrush waveform you can find the parameters necessary for determining maximum cycle rate.

Figure 6. Maximum Cycle Rate Derating Factor by Pulse Width

Determining the Maximum Cycle Rate

Complete the following steps and use the figures above to determine the maximum cycle rate at which a channel can be switched when the peak impulse current value and duration are known.

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 on the Maximum Cycle Rate Derating Factor by Pulse Width graph 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:
$MaxCycleRate = C R 50_{μ s} \cdot D F (H z)$

where CR₅₀_μs = max cycle rate for a 50 μs wide inrush current pulse in Hz

DF = derating factor

Note If the peak impulse current does not exceed 40 A, do not derate the maximum cycle rate below 31 Hz.

Example 1—Single Path Closed

For switching a steady state current of 4 A into a load with peak inrush current of 180 A that lasts for 400 μs, choose the 200 A graph line in the Maximum Cycle Rate graph. Find the y-axis value that corresponds to the 16 A load current (650 Hz). Then find the derating factor in the Maximum Cycle Rate Derating Factor by Pulse Width graph that corresponds to 400 μs (0.1).

The maximum cycle rate at which this signal can be switched by the module is calculated as follows:

MaxCycleRate = 650 H z \cdot 0.1 ≅ 65 H z

For switching a steady state current of 15 A into a load with peak inrush current of 180 A that lasts for 400 μs while another channel is also carrying 25 A, choose the 200 A graph line in the Maximum Cycle Rate for Multiple Paths Closed graph. Find the y-axis value that corresponds to the 15 A load current (300 Hz.) Then find the derating factor in the Maximum Cycle Rate Derating Factor by Pulse Width graph that corresponds to 400 μs (0.1).

The maximum cycle rate at which this signal can be switched by the module is calculated as follows:

MaxCycleRate = 300 H z \cdot 0.1 = 30 H z
