Introduction

The NI TB-2631B terminal block installs in front of the NI PXI-2530B switch module. The

NI TB-2631B has screw terminals to connect signals to the switch. Screw terminals for the trigger

input and trigger output signals are also available. The NI TB-2631B is designed for use with the

NI PXI-2530B and is not compatible with the NI PXI-2530.

1. Unpack the Terminal Block

To avoid damage when you handle the terminal block, take the following precautions:

Caution Never touch the exposed pins of connectors.

• Ground yourself using a grounding strap or by touching a grounded object.

• Touch the antistatic package to a metal part of the chassis before you remove the terminal block

from the package.

Remove the terminal block from the package and inspect the terminal block for loose components or

any sign of damage. Notify NI if the terminal block appears damaged in any way. Do not install a

damaged terminal block on a switch module.

Store the terminal block in the antistatic package when not in use.

2. Verify the Components

Make sure you have the following:

❑NI TB-2631B terminal block

❑PXI chassis

❑NI PXI-2530B switch module

❑1/8 inch flathead screwdriver

3. Connect Signals

Caution To ensure the specified EMC performance, operate this product only with shielded cables

and accessories.

To connect signals to the terminal block, complete the following steps:

1. Remove the terminal block top cover screws with a flathead screwdriver.

2. Gently lift the terminal block top cover off the terminal block.

3. Loosen the two screws on the strain-relief bar, leaving plenty of space for the signal cables.

4. Prepare the signal cable by stripping the insulation no more than 3/16 of an inch.

5. Pull the signal cables through the strain-relief opening shown in Figure 1.

6. Connect the cables to the terminals by inserting the stripped end of the cable into the terminal.

Secure the connection by tightening the screw for each terminal. When connecting the signals, refer

to the connection diagram in Figure 2.

Note When connecting signals to the NI TB-2631B, refer to Tables 1 and 2 to determine where to

connect signals for the chosen topology.

7. Connect the shield of the signal cable to the safety ground lug shown in Figure 1.

8. Tighten the two screws on the strain-relief bar, securing the signal cables.

9. Replace the terminal block top cover to the terminal block.

10. Secure the terminal block top cover with the top cover screws.
