PXIe-2593 Specifications

This document lists specifications for the PXIe-2593. All specifications are subject to change without notice.

About These Specifications

Specifications characterize the warranted performance of the instrument under the stated operating conditions. Data in this document are Specifications unless otherwise noted.

Typical Specifications are specifications met by the majority of the instrument under the stated operating conditions and are tested at 23 °C ambient temperature. Typical specifications are not warranted.

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

Caution The protection provided by the PXIe-2593 can be impaired if it is used in a manner not described in this document.

Input Characteristics

Maximum switching voltage

150 V, CAT I (channel-to-channel and channel-to-ground)

Caution This module is rated for Measurement Category I. It is intended to carry signal voltages no greater than 100 Vrms, 150 V pk, or 150 VDC. This module can withstand up to 800 V impulse voltage. 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 VAC or 230 VAC.
Caution When hazardous voltages (>42.4 Vpk/60 VDC) are present on any relay terminal, safety low-voltage ( ≤ 42.4 Vpk/60 VDC) cannot be connected to any other relay terminal.

Maximum switching current (per channel)

0.5 A

Maximum carry current (per channel)

1 A

Simultaneous channels at maximum current

Up to 2

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

Maximum switching power (per channel)

10 W

Note NI recommends against switching active RF signals. As a relay actuates, the channel is momentarily unterminated. Some RF sources can be damaged by reflections if their outputs are not properly terminated. Refer to your RF source documentation for more information.

Minimum switch load

10 μA, 10 mV

Maximum RF carry power (per channel)

10 W up to 500 MHz

DC path resistance

Initial

<1.0 Ω

End-of-life

≥2.0 Ω

Path resistance is a combination of relay contact resistance and trace resistance. Contact resistance typically remains low for the life of a relay. At the end of relay life, the contact resistance rises rapidly above 1.0 Ω.
