Input Characteristics


Maximum switching voltage, channel-to-channel	150 V
Maximum switching voltage, 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.

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 V DC) are present on any channel, safety low-voltage (≤42.4 Vpk/60 V DC) 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 switching current	2 A (per channel)
Maximum carry current	2 A (per channel)
Minimum switch load	20 mV/1 mA

Note The PXIe-2526 is not recommended for 2-wire resistance measurements.

Notice 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, warranted
DC path resistance, 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 at ≥1.5 Ω.


Thermal EMF	<10 µV
