Introduction
The TB-2706 is a terminal block assembly consisting of a printed circuit board, 70 screw terminals, and
a metal enclosure with strain relief hardware. The terminal block assembly connects directly to the front
panel of National Instruments PXI-622x, PXI-625x, PXIe-625x, PXI-628x, and PXI-6143 devices,
eliminating the need for an external cable.
The TB-2706 allows you to easily connect analog input, analog output, counter/timer, and digital I/O
signals to your National Instruments device. The 70 screw terminals allow access to every pin on the
connector, plus two shield screw terminals for use with a shielded cable. For MSeries devices with
twoconnectors, this terminal block allows access to every pin on Connector 0, plus two shield screw
terminals for use with a shielded cable, but makes Connector 1 inaccessible.
Caution The TB-2706 is not designed for input voltages greater than 42Vpk/60 VDC, even if you
install a voltage divider that reduces the voltage to within the input range of the DAQ device. Input
voltages greater than 42Vpk/60 VDC can damage the TB-2706, any device connected to it, and the
host computer. Overvoltage also can cause an electric shock hazard for the operator. National
Instruments is not liable for damage or injury resulting from such misuse.
