National Instruments PXI-2569 Relay Module

The NI PXI-2569 (Part Number: 778572-69) is a 100-channel, universally useful switch module including SPST (Form A) armature transfers, which is well-suited for medium-control of robotized test loads. The device has a switch bandwidth of 20 MHz with a scan rate of 145 cycles per second. This model includes LabVIEW and LabWindows/CVI, which are innovative program development software bundles for information acquisition and control applications. LabVIEW utilizes graphical programming, while LabWindows/CVI improves conventional programming languages. The two bundles incorporate broad libraries for information acquisition, instrument control, data analysis, and graphical data presentation. Utilizing LabVIEW or LabWindows/CVI can fundamentally diminish the development time for the user’s information acquisition and control application.

In this model, each channel interfaces with the corresponding common by shutting its relay. The relay name depends on the corresponding signal name. For instance, the relay connecting CH9 to COM9 is CH9. The user can have numerous channels associated with the corresponding commons. This instrument allows the user to utilize the driver programming to arrange the switch card for ceaseless or one-time filtering. In ceaseless examining, the switch card goes through the output list until the user disables scanning. For one-time scanning, the switch card goes through the scan list just once. The user can also utilize a programming summons to clear the output list or reset it to the start. The device has a channel-to-channel maximum switching voltage of 100 V, and a channel-to-ground maximum switching voltage of 100 V, CAT 1. It has a maximum input current of 1 A per channel and a maximum switching input power of 60 W per channel.

The NI PXI-2569 can utilize an outside trigger input to progress between scan setups in a scan list. Utilizing the driver software, the user can arrange the change card to course the outer trigger from any of the PXI TTL trigger lines or the PXI star trigger. On the other hand, the user can utilize a software command to trigger the switch card. The device weighs 10.2 oz., and measures 8.5 x 0.8 x 5.1 in. in dimensions. It has a recommended operating temperature range of 0 °C to 55 °C.
