Specifications characterize the warranted performance of the instrument under the following operating conditions:
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.
All input characteristics are DC, ACrms, or a combination unless otherwise specified.
Maximum switching voltage |
50 VDC, 30 V ACrms, CAT I[1] |
This module is rated for Measurement Category I and intended to carry signal voltages no greater than 30 Vrms/42 Vpk/50 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.
Maximum continuous current |
10 A (per channel or common, switching or carry) |
Maximum pulsed current |
50 A (for 600 μs max) |
Maximum switching power (per channel) |
500 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).

Typical bandwidth (50 Ω system) |

To help protect against fault conditions, the PXIe-2512 incorporates circuitry to detect overtemperature conditions.
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.
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 graph line in the Maximum Cycle Rate graph. 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 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:

Certain applications may require additional time for proper settling. Refer to the NI Switches Help at ni.com/manuals for more information about including additional settling time.
Typical relay life |
Unlimited, when operated within specified limits |

The PXIe-2512 can recognize trigger pulse widths less than 150 ns if you disable digital filtering. Refer to the NI Switches Help at ni.com/manuals for information about disabling digital filtering.
