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 Vpk/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 Vpk/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.

Safety Information
Cautions Do not operate the device in an explosive atmosphere or where there may be flammable
gases or fumes.
Do not operate damaged equipment. The safety protection features built into this device can become
impaired if the device becomes damaged in any way. If the device is damaged, turn the device off and
do not use it until service-trained personnel can check its safety. If necessary, return the device to
National Instruments for service and repair to ensure that its safety is not compromised.
Do not operate this equipment in a manner that contradicts the information specified in this
document. Misuse of this equipment could result in a shock hazard.
Do not substitute parts or modify equipment. Because of the danger of introducing additional
hazards, do not install unauthorized parts or modify the device. Return the device to National
Instruments for service and repair to ensure that its safety features are not compromised.
You must insulate all of your signal connections to the highest voltage with which the TB-2706 can
come in contact.
Connections, including power signals to ground and vice versa, that exceed any of the maximum
signal ratings on the terminal block can create a shock or fire hazard, or can damage any or all of the
boards connected to the host computer, and the terminal block. National Instruments is not liable for
any damages or injuries resulting from incorrect signal connections.
Clean the module and accessories by brushing off light dust with a soft non-metallic brush. Remove
other contaminants with a stiff non-metallic brush. The unit must be completely dry and free from
contaminants before returning it to service.

Connecting the Signals
Refer to Figure 1 as you complete the following steps to connect signals to your terminal block.
Figure 1. TB-2706 Parts Locator Diagram
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 Vpk/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 Vpk/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.
