The National Instruments SWB-2810 Matrix Module is specifically designed for use with the National Instruments SwitchBlock, featuring part numbers 781421-10 and 781420-10. This 1 A, 4 x 43 matrix module supports switching capabilities of up to 150 V or 1 A, with a maximum power rating of 20 watts. Within a single carrier, the SWB-2810 can be configured to function as a 4 x 258 matrix, and it can be further expanded to accommodate up to 4 x 1032 matrices within a single PXI chassis. By combining the SWB-2810 with additional National Instruments SWB cards, users can create a tailored multicard SwitchBlock device.

Equipped with reed relays utilizing Iridium contact material, the relays enable rapid actuation, with operation or release times of less than one millisecond when activating up to eight relays, and under two milliseconds for up to 50 relays. The module requires 20 watts at 5 V or 5 watts at 3.3 V for operation, while a total of 176 relays can be driven simultaneously. With a 96-position SCSI I/O connector, the SWB-2810 is a reliable switching solution characterized by its high expected electrical and mechanical relay life. Each relay consumes up to 50 mW to operate, and the cumulative power draw for the relays should not exceed 8.8 watts. The SWB-2810 is classified as a Category I device, suitable for use in systems with voltages below 150 V. The unit measures 4.4 inches by 0.5 inches by 6.7 inches and weighs 8.5 ounces, and comes with a 2 to 3 year warranty.
