The National Instruments PXI-2569 Relay Module (Part Number: 778572-69) is a versatile 100-channel switching solution ideal for medium-control applications in automated test environments. It features single-pole, single-throw (SPST) armature transfers, offering a switch bandwidth of 20 MHz and a scan rate of 145 cycles per second. This module is compatible with the LabVIEW and LabWindows/CVI program development environments, which streamline the integration of data acquisition and control systems using either graphical or traditional programming methodologies. Each channel integrates with its corresponding common by closing its relay, enabling flexible configurations where multiple channels can share the same common signal, enhancing operational efficiency.

Users can configure the relay module for continuous or one-time scanning modes, allowing it to process through an output list continuously until disabled or to accomplish a single pass through the list. The ability to reset or clear the output list through programming commands further enhances usability. The PXI-2569 supports a maximum switching voltage of 100 V for both channel-to-channel and channel-to-ground connections, with a maximum input current of 1 A and switching power of 60 W per channel. Additionally, it includes an external trigger input for transitioning between scan setups, which can be directed from any of the PXI TTL trigger lines or the PXI star trigger, or alternatively activated via software commands.

With dimensions of 8.5 x 0.8 x 5.1 inches and a weight of 10.2 ounces, the module is compact and easy to integrate. It operates within a recommended temperature range of 0 °C to 55 °C. The PXI-2569 is reinforced by a three-year warranty and comes with user and maintenance manuals available for download. For pricing, please contact a sales representative directly.
