Description
The SWB-2817 Matrix Module, with part numbers 781420-17 and 781421-17, is a versatile component designed by National Instruments for high-power applications. This module is configured in a 16 rows by 22 columns (16×22) 1-wire matrix and offers distinct options for row access.
It can be expanded in a single carrier configuration to 16×132 or up to 16×528 in a single PXI chassis, providing scalability for complex setups. Its 5 MHz bandwidth capability ensures it can handle high-speed signals effectively.
The SWB-2817 can switch up to 100 VDC or 70 VAC between rows and columns and supports a maximum of 61 simultaneous relays. The relay operation and release times are impressively quick, with less than 1 ms for up to 8 relays and less than 2 ms for up to 50 relays.
The module manages a maximum switching current of 250 mA and a carry current of 300 mA, with a maximum power consumption for switching being capped at 3 W, which highlights its efficiency in power usage.
