Description
The National Instruments SWB-2816 is a highly versatile Reed Matrix Module for SwitchBlock, designed to meet a wide range of applications within the PXI Switches category. It is uniquely identified by its part numbers 781421-16 and 781420-16.
This module boasts an impressive 8×46 (8 rows and 46 columns) 1-wire matrix configuration, making it ideal for complex switching setups. It is designed to occupy only 1 slot within a SwitchBlock carrier module, ensuring a compact and efficient use of space in your setup. The SWB-2816 operates in various modes, including as an independent single relay card, or as an expandable module capable of scaling up to 8 x 276 in a single carrier or up to 8 x 1104 in a PXI chassis.
Applications of the SWB-2816 are broad and include the transfer of signals from digital multimeters, oscilloscopes, power supplies, and waveform generators. This module can be customized and combined with other SWB-2816 modules to create a tailored multi-card assembly that meets specific user needs.
From a technical perspective, the SWB-2816 shines with a typical bandwidth of > 8 MHz, supporting switching voltages of up to 100 VDC. Each channel can handle a switching current of 0.25 A and a carry current of 0.30 A. These specifications underscore the module’s robust performance and flexibility, making it a valuable asset for a wide range of high-performance testing and measurement tasks.
