The National Instruments SWB-2817 Matrix Module is an advanced relay matrix solution designed for use in SwitchBlock systems, offered with two distinct part numbers: 781420-17, which features row access, and 781421-17, which does not. This module is particularly suited for high-power applications and boasts a configuration of 16 rows and 22 columns arranged in a 1-wire matrix layout. The SWB-2817 is engineered for versatility, allowing expansion in both single carrier and PXI chassis setups, reaching up to 16x132 in single carrier configurations and up to 16x528 in PXI configurations. It simplifies wiring and enhances flexibility in system interconnections. The module plays a crucial role in signal routing among power random waveform generators, digital oscilloscopes, and multimeters during testing operations. The SWB-2817 is a compact, single-slot module capable of handling a maximum switching voltage of 100 VDC or 70 VAC, with an operational bandwidth of 5 MHz. The module can simultaneously manage up to 61 relays, with a relay operating and releasing time of less than 1 ms for configurations of up to 8 relays, and less than 2 ms for up to 50 relays. It accommodates a switching current of 250 mA and a carry current of 300 mA, while the maximum power consumption is limited to 3 W. The physical dimensions of the module are 4.4 inches by 0.5 inches by 6.7 inches, and it weighs 11.3 oz. A comprehensive user manual and maintenance guide are available for download, and inquiries regarding pricing should be directed to a National Instruments sales representative. The SWB-2817 also comes with a warranty period ranging from two to three years.
