Description
The NI 2810B 4×43, 1 A Reed Matrix for NI SwitchBlock, part numbers 781421-10 and 781420-10, falls under the category of PXI Switches with the model number SWB-2810. This device is designed to provide exceptional switching capacity, supporting up to 150 V or 1 A, 20 watts max, making it an ideal solution for a wide range of testing and measurement applications.
One of the key features of this switch is its configuration options. It can be set up as a 4 x 258 matrix in a single carrier, but for more extensive needs, it’s expandable up to a 4 x 1032 matrix within a single PXI chassis. This scalability ensures that the switch can adapt to both current and future requirements, providing an efficient and cost-effective solution.
The SWB-2810 utilizes Reed relays with Iridium contact material for its switching mechanism. These relays are known for their durability and reliability, with an operating/release time of less than 1 ms for up to 8 relays, and less than 2 ms for up to 50 relays, ensuring quick and precise operations.
From a power perspective, the device requires 20 watts at 5 V and 5 watts at 3.3 V for the carrier. It is equipped with a 96-position SCSI I/O connector, enabling easy integration with a wide array of systems. Despite its robust capabilities, it supports a total of 176 relays simultaneously, with each relay consuming 50 mW, ensuring the total does not exceed 8.8 watts.
Classified under Device Category CAT I, the SWB-2810 is suitable for usage in systems with voltages below 150 V, making it an excellent choice for a variety of low-voltage applications. Whether for research, development, or manufacturing testing, this PX
