National Instruments TB-2606

The National Instruments TB-2606 Matrix Terminal Block is engineered to facilitate connections for the NI PXI-2501 and PXI-2503 modules. Designed under part number 777879-01, this terminal block employs a printed circuit board layout that enables direct connections to the input/output terminals via screw terminals. The TB-2606 requires an analog bus accessory for interfacing with multiple cards, and it supports a 6x4 matrix configuration, essential for organizing wiring connections of PXI multiplexers. For enhanced connectivity, the terminal block includes two additional connectors for low-voltage analog bus applications alongside adjacent switch cards. The unit is compatible with various tools for assembly and installation, including a No. 1 Phillips screwdriver and wire strippers. While the TB-2606 has been marked as obsolete by National Instruments, it remains available for purchase and repairs through Apex Waves. This terminal block conforms to operational voltage limitations, ensuring that inputs remain within 30 Vrms or 60 VDC of ground. The dimensions of the TB-2606 are 3.3 by 4.2 by 0.8 inches, and it comes backed by a 2-3 year warranty, with user and maintenance manuals available for download.
