The National Instruments SWB-2815 Matrix Module for SwitchBlock (Part Numbers: 781421-15 and 781420-15) is a sophisticated 0.3 A reed relay module designed for integration within a PXI-based matrix system. Featuring high-reliability Ruthenium contacts, this module is rated for approximately 250 million cycles, ensuring durability in demanding applications. The SWB-2815 is capable of driving up to 61 relays simultaneously, supporting a maximum switching voltage of 100 VDC and a switching current of 0.25 A per channel, with an impressive maximum switching power of 3 watts per channel or per crosspoint.

It is important to note that the SWB-2815 functions as a card and requires mounting on a compatible carrier device, specifically the NI-2800, which is sold separately. The NI-2800 accommodates six slots, allowing for configurations that include multiple matrix modules. The SWB-2815 is engineered to support a 4 x 86 matrix in a 1-wire configuration; however, additional configurations can be achieved by utilizing two SWB-2815 modules or other types of SwitchBlock modules.

As a Category I device, the SWB-2815 is designed to safely manage signal voltages under 100 VDC or 70 Vrms and has been tested for surge withstand capability up to 500 V. This module has dimensions of 4.4 inches by 0.5 inches by 6.7 inches and weighs 11.3 ounces.
