The National Instruments SWB-2814 Matrix Module, identified by part numbers 781420-14 and 781421-14, is an integral component of the NI SwitchBlock system, specifically engineered for a 2-wire, 8 x 9 configuration. As a matrix module, the SWB-2814 is not a standalone switching device; it operates in conjunction with a PXI Carrier Module, which serves as the hosting infrastructure for this module along with other comparable SwitchBlock components. The SWB-2814 occupies one of the six slots available in the carrier module, allowing for versatile configurations by integrating additional matrix modules.

This module features field-replaceable relays and is equipped with advanced relay health monitoring capabilities. Users can utilize the NI Switch Health Center software to assess the operational status of the relays embedded in the module, enabling various function tests to ensure reliability and performance. A variant of the SWB-2814 also provides access to the analog bus for expanded functionality. With an integrated relay monitoring chip, the module continuously tracks the health of the relays and delivers critical information directly to the user. Easy installation is facilitated by simply plugging the module into an available PXI Carrier Module slot. The SWB-2814 supports a maximum bandwidth of up to 10 MHz, making it suitable for a wide range of automated measurement and testing applications. Dimensions of the SWB-2814 are 4.4 in. x 0.5 in. x 6.7 in., and it weighs 8.5 oz. A detailed user manual and maintenance manual are available for download, and potential buyers are encouraged to contact a sales representative for pricing information. This product is backed by a 2-3 year warranty, ensuring reliability and support.
