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.

Caution The protection provided by the NI 2526 can be impaired if it is used in a
manner not described in this document.
Input Characteristics
Maximum switching voltage
....................................................................Channel-to-channel 150 V
....................................................................Channel-to-ground 150 V, CAT O
Note This module is rated for Measurement Category I. It is intended to carry
signal voltages no greater than 150 V. 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. Refer to the Read Me
First: Safety and Electromagnetic Compatibility document for more information
about measurement categories.
Measurement Categories CAT I and CAT O (Other) are equivalent and are for measurements
performed on circuits not directly connected to the electrical distribution system referred to as
MAINS voltage. This category is for measurement of voltages from specially protected
secondary circuits. Such voltage measurements include signal levels, special hardware,
limited-energy parts of hardware, circuits powered by regulated low-voltage sources, and
electronics.
Caution When hazardous voltages (>42.4 Vpk/60 VDC) are present on any
channel, safety low-voltage (≤42.4 Vpk/60 VDC) cannot be connected to any other
channel.
............................................................................Maximum switching power 60 W, 62.5 VA
Caution The switching power is limited by the maximum switching current, the
maximum voltage, and must not exceed 60 W, 62.5 VA.
............................................................................CH-COM DC isolation resistance >1 GΩ, typical at 25 °C
Maximum current
....................................................................Switching 2 A (per channel)
....................................................................Carry 2 A (per channel)
............................................................................Minimum switch load 20 mV/1 mA
Note The NI 2526 is not recommended for 2-wire resistance measurements.

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 ≥ 1.5 Ω
DC path resistance is a combination of relay contact resistance and trace resistance. Measure
path resistance by combining the resistance of the high and low signal paths from one row to
one column. Contact resistance typically remains low for the life of a relay. At the end of relay
life, the contact resistance rises rapidly above ≥ 1.5 Ω.
............................................................................Thermal EMF <10 µV
RF Performance Characteristics
............................................................................Bandwidth (-3 dB, typical at 23 ºC)
50 Ω termination
≤10 MHz
Open channel isolation (typical at 23 ºC) 50 Ω
termination
....................................................................10 kHz ≥ 67 dB
....................................................................100 kHz ≥ 49 dB
....................................................................1 MHz ≥ 29 dB
Dynamic Characteristics
Relay operate time
....................................................................Typical 1 ms
....................................................................Maximum 3.1 ms
....................................................................Simultaneous drive limit 82 relays
Expected relay life
....................................................................Mechanical 1 × 108 cycles
Electrical
............................................................
≤30 mV, ≤10 mA resistive 2.5 × 106 cycles
............................................................30 V, 1 A 5 × 105 cycles
NI PXIe-2526 Specifications | © National Instruments | 3

............................................................30 V, 2 A 1 × 105 cycles
