The National Instruments PXI-2585 (Part Number: 778572-85) is a robust 12 A, 1-Wire, 10-Channel Multiplexer Switch Module designed to meet the demands of high-power applications, including automotive, battery, and power supply testing. This module can be configured as a 10x1 multiplexer, providing high isolation voltage and low contact resistance, facilitating the acquisition of up to 300 V channel-to-channel and 300 V (Measurement Category II) channel-to-ground maximum switching voltage. In AC applications, the PXI-2585 supports a maximum switching power of 3 kVA per channel, accommodating frequencies up to 60 Hz.

Equipped with electromechanical single-side stable relays using silver-nickel contact material, the relays in the PXI-2585 actuate within a maximum of 15.4 milliseconds. The expected lifespan of the relays is notable, with mechanical cycles rated at 1 × 10^7 and electrical cycles at 1 × 10^5 (@ 30 V DC, 10 A DC resistive) and 3 × 10^4 (@ 30 V DC, 12 A DC resistive). This compact module occupies a single 3U PXI slot and measures 21.6 cm × 2.0 cm × 13.0 cm. It features a Positronic GMCT series plug I/O connector with 20 positions for versatile connectivity. The PXI-2585 supports both input and output trigger signals for enhanced integration into complex measurement setups. Additional accessories, such as 1M/2M switch cables and custom cable kits, are available separately to complement the PXI-2585. A user manual and maintenance manual are available for download, and pricing can be obtained by contacting a sales representative. This module is backed by a 2-3 year warranty to ensure reliability and support.
