Description
The NI TB-2644B Terminal Block is a versatile device with part numbers 782385-09 (without protection resistors) and 782385-10 (with 100 Ohm protection resistors), designed to be compatible with the PXIe/PXI-2532B Switch Module. It supports multiple configurations, including a 1-wire, dual 8 x 32 matrix, and a 2-wire, 8 x 32 matrix, allowing for flexible system design.
Connections to the Terminal Block are made through ribbon cable headers, ensuring a reliable and secure connection to the switch module. For applications requiring protection against capacitive loads, the version with 100 Ohm protection resistors (part number 782385-10) is an ideal choice, safeguarding the relays within the module.
The Terminal Block features 2 row headers and 2 column headers, providing ample connection points for a variety of setup configurations. Additionally, a screw-enforced strain-relief bar adds durability and stability to the cable connections. The top cover of the NI TB-2644B is designed to be removable, which allows for easy access to the connection headers when adjustments or maintenance are required.
