The National Instruments SWB-2813 is a 2-Wire Matrix Module designed for use within the 4 x 21 topology of NI SwitchBlock systems. This module, referenced by part numbers 781420-13 and 781421-13, functions exclusively in conjunction with a carrier device such as the NI-2800, a PXI-based carrier module. The SWB-2813 cannot operate as a standalone switching device, ensuring tailored deployment for specific applications within custom switching systems. It incorporates mechanical reed relays with iridium contacts, optimized for frequent operation.

The integrated 96-position I/O connector facilitates simplified wiring and allows users to alter internal connection routes without manual intervention, enhancing system flexibility. This design enables the connection of channels between different rows and columns, effectively customizing test configurations with ease. Supporting advanced features such as relay health monitoring, hardware triggering, and relay count tracking, the SWB-2813 delivers functionality with a maximum bandwidth of 8 MHz. It occupies a single slot in a compatible carrier module and supports a maximum switching current of 1 A and a maximum switching voltage of 150 V. The module dimensions are 4.4 in. × 0.5 in. × 6.7 in., with a weight of 8.5 oz. For detailed operation and maintenance guidance, user manuals are available for download.
