Description
The SWB-2810 4×43, 1 A Reed Matrix for NI SwitchBlock is identified by part numbers 781421-10 and 781420-10. This module is capable of handling a maximum voltage of 150 V and a current of up to 1 A, with a maximum power capacity of 20 watts.
Designed for flexibility, the module supports a configurable matrix size of 4 x 258 in a single carrier. For larger configurations, it can be expanded within a single PXI chassis to a maximum matrix size of 4 x 1032. At the heart of its reliable operation are the relay contacts, which are made from iridium, ensuring durability and longevity.
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. Power requirements for the carrier are flexible, requiring 20 watts at 5 V or 5 watts at 3.3 V, making it adaptable to various power supplies.
The module interfaces with systems through a 96-position SCSI I/O connector, providing a robust and reliable connection. It supports the simultaneous operation of up to 176 relays, with each relay consuming up to 50 mW. Despite this capability, the total power consumption for all relays is designed not to exceed 8.8 watts, ensuring efficient operation.
Finally, this module is classified as a CAT I device, indicating its suitability for measurements performed in circuits not directly connected to the main. This categorization highlights its safe application in environments that require precision and protection against high-voltage transients.
