National Instruments PXIe-2526 PXI Multiplexer Switch Module

The PXIe-2526 (Part Number: 780587-26, 155043A-01L) is an advanced Multiplexer Switch Module from National Instruments. It incorporates two different topologies, including a 1-wire 158 x 1 or 2-wire 79 x 1 multiplexer technology. The PXIe-2526 is an ideal switch module to operate with automated test systems. It makes the whole process of routing signals within these test systems seamless and enables users to achieve highly accurate test results to meet industrial requirements. The NI PXIe-2526 Multiplexer Switch Module comes with built-in electromechanical relays to perform quick switching operations. The instrument makes use of one of the aforementioned topologies to implement switching.

The PXIe-2526 module also implements a relay counting mechanism to fulfill relay monitoring requirements. The initial DC path resistance of the device is less than 0.5 Ohms. The end of life DC path resistance is greater than or equal to 1.5 Ohms. The value for thermal EMF of the switch module is less than 10 micro-volts. The NI PXIe-2526 Switch Module also incorporates RF measurement capabilities. It can offer bandwidth less than or equal to 10 MHz at -3 dB and 23 degree-centigrade.

The PXIe-2526 features a typical relay operation time of one millisecond. The simultaneous drive limit is up to 82 relays. The module weighs 230 grams, ensuring it is portable and easily carried anywhere it is needed. The normal operating temperature range is 0 to 55 degrees Celsius. The relative humidity range for the NI PXIe-2526 Multiplexer Switch Module is 10% to 90%. This module also has protection against shock and vibrations.
