Screw Terminal, PCB, PXI Module Multiplexer Terminal Block—The TB-2606 includes a printed circuit board (PCB) with screw terminals. It provides the necessary routing to configure the PXI-2501 or PXI-2503 PXI Multiplexer Switch Modules as a 6×4 two-wire matrix. You can directly connect the TB-2605 to the front panel I/O connectors of the PXI-2501 or PXI-2503. The front side of the TB-2606 features two additional connectors for connecting to the analog bus. You can use the included low-voltage AB plug to connect the analog bus of adjacent PXI Multiplexer Switch Modules.
