NI PXI-2523 Specifications
26-Channel DPDT Relay Module
This document lists specifications for the NI PXI-2523 general-purpose relay module. All
specifications are subject to change without notice. Visit ni.com/manuals for the most
current specifications.
Caution The protection provided by the NI PXI-2523 can be impaired if it is used
in a manner not described in this document.
Topology ........................................................... 26-channel DPDT, non-latching
Refer to the NI Switches Help for detailed topology information.
About These Specifications
Specifications characterize the warranted performance of the instrument under the stated
operating conditions.
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.
Refer to the Read Me First: Safety and Electromagnetic Compatibility
document for important safety and electromagnetic compatibility information. To
obtain a copy of this document online, visit ni.com/manuals, and search for the
document title.
Caution
To ensure the specified EMC performance, operate this product only with
shielded cables and accessories.
Caution
Input Characteristics
Maximum switching voltage
Channel-to-channel................................... 100 V
Channel-to-ground.................................... 100 V, CAT I
This module is rated for Measurement Category I and intended to carry
signal voltages no greater than 100 V. This module can withstand up to 500 V impulse
voltage. Do not use this module for connection to signals or for measurements within
Caution
Categories II, III, or IV. Do not connect to MAINS supply circuits (for example, wall
outlets) of 115 or 230 VAC. Refer to the Read Me First: Safety and Electromagnetic
Compatibility document for more information on measurement categories.
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.
Caution
The switching power is limited by the maximum switching current, the
maximum voltage, and must not exceed 60 W, 62.5 VA.
Caution
Maximum switching power
(per channel) .....................................................60 W, 62.5 VA (DC to 60 Hz)
Maximum current
(switching or carry, per channel) ......................2 A
Simultaneous channels at maximum
current (≤55 °C) ................................................26
Minimum switching conditions ........................20 mV/1 mA
Note 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.
For more information about transient suppression, visit ni.com/info and enter the
Info Code relayflyback.
DC path resistance
Initial .........................................................<0.5 Ω
End-of-life................................................. ≥1.0 Ω
DC path resistance typically remains low for the life of the relay. At the end of relay life, the path
resistance rises rapidly above 1 Ω. Load ratings apply to relays used within the specification
before the end of relay life.
Thermal EMF (typical at 23 °C) .......................12 µV

1-wire ........................................................≤70 MHz
2-wire ........................................................≤35 MHz
Crosstalk (typical at 23 °C, 50 Ω termination)
Channel-to-channel
10 kHz...............................................≤-65 dB
100 kHz............................................. ≤-45 dB
