National Instruments PXIe-2525 PXI Multiplexer Switch Module

The PXIe-2525 (Part Number: 780587-25) is a 64-Channel high-performance Multiplexer Switch Module from National Instruments. This module implements an efficient mechanism to route signals within an automated test system. The instrument comes in the 2-wire topology and incorporates 16 bank 4x1, octal 8x1, quad 16x1, dual 32x1, and 64x1 configuration schemes. It enables the NI PXIe-2525 to implement the switching mechanism for various testing requirements. The instrument also has the built-in relay counting mechanism for relay monitoring. It offers the channel to channel maximum switching voltage of up to 150 volts. The channel to ground switching voltage specification is also 150 volts.

The NI PXIe 2525 Multiplexer Switch Module incorporates CH-COM DC isolation resistance. It has the typical value of 1 Giga-ohms 25 degrees Celsius. The bandwidth for RF measurements is less than or equal to 10 MHz. The built-in relays of the module are electromechanical and non-latching. These relays are field replaceable. The contact material of the relays is palladium-ruthenium and covered in gold. The PXI express device has a power requirement of 20 W at 12 V, and 3.4 W at 3.3 V. In addition, the NI device is run using the NI-SWITCH driver software.

The PXIe-2525 Multiplexer Switch Module has the pollution degree level of 2 and is meant for indoor use only. The instrument has various accessories available for purchase separately, such as switch cables of different lengths and a relay replacement kit. These accessories enable the users to set up the instrument to carry out measurements with ease. The instrument also complies with various safety standards, including IEC 61010-1, EN 61010-1, UL 61010-1, and CSA 61010-1 specifications.

The NI device weighs 8.1 oz, and measures 8.5 x 0.8 x 5.1 in. in physical dimensions. It has a recommended operating temperature range of 0 °C to 55 °C, a storage temperature range of -40 °C to 71 °C, non-condensing operating and storage humidity ranges of 10% to 90% RH and 5% to 95% RH respectively, operating and non-operating random vibrations of 0.3 grms and 2.4 grms respectively–all at a frequency range of 5 to 500 Hz.
