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 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.

What You Need to Get Started

You need the following to set up and use your terminal block:

❑

1. Remove the terminal block cover by unscrewing the top cover screw using the 0.10 in. slotted

screwdriver.

Note Your kit contains a pinout label for M Series devices only, shown in Figure 2. This label,

adhered to the inside of the cover, is a pin number-to-signal name reference. For PXI-6143 pin

connections, refer to Figure 3 or the S Series User Manual.

2. Loosen or remove the strain-relief bar by loosening the two strain-relief screws with the

Phillips-head screwdriver.

3. Use wire cutters and wire insulation strippers to strip no more than 7 mm of insulation from the

wire ends.

4. Loosen the screws in the screw terminals with the 0.10 in. slotted screwdriver.

5. Insert the stripped wires into the screw terminals. Tighten the screws with the 0.10 in. slotted

screwdriver. No bare wire should extend past the screw terminal. Exposed wire increases the risk

of short circuits and failures.

6. Tighten or replace the strain-relief screws.

7. Replace the terminal block cover by sliding the indentations on the cover under the tabs on the base.

Tighten the top cover screw.

Installing the Terminal Block

Refer to Figure 4 as you complete the following steps to connect the terminal block to the PXI/PXIe

module I/O connector.

Figure 4. Connecting the TB-2706 to an M Series or PXI-6143 Device

Caution The connectors of both the PXI/PXIe module and the terminal block are polarized. You can

attach them in only one way. Do not force the terminal block when inserting it into or removing it

from the PXI/PXIe module I/O connector. Make sure that the chassis is powered off before inserting

the PXI/PXIe module.

1. Install the PXI/PXIe module into the chassis and tighten the two module screws. You must install

the TB-2706 terminal block on the PXI/PXIe module after the module is installed in the chassis.

2. Guide the terminal block onto the connector.

3. Tighten the two terminal block mounting screws.

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.
