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-622

x

, PXI-625

x

, PXIe-625

x

, PXI-628

x

, 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 M Series devices with 
two connectors, 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 42 V

pk

/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 42 V

pk

/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.
