NI TB-2636

4×32 2-Wire Terminal Block for the NI PXI-2529

This document describes how to install and connect signals to the

National Instruments TB-2636 terminal block. Refer to the NI Switches

Getting Started Guide to determine when to install the NI TB-2636.

Introduction

The NI TB-2636 terminal block installs in front of the NI PXI-2529 switch

module and has screw terminals that provide access to the rows and

columns of the matrix.

Caution This terminal block is rated for Measurement Category I and intended to carry

signal voltages no greater than 150 V. This module can withstand up to 800 V impulse

voltage. Do not use this module for connection to signals or for measurements within

Categories II, III, or IV. Do not connect to MAINS supply circuits (for example, wall

outlets) of 115 or 230 VAC. Refer to the Read Me First: Safety and Radio-Frequency

Interference document for more information on measurement categories.

When module terminals are hazardous voltage LIVE (> 42.4 Vpk/60 VDC), you must

ensure that devices and circuits connected to the module are properly insulated from

human contact.

1. Unpack the Terminal Block

The terminal block is shipped in an antistatic package to prevent

electrostatic discharge (ESD) that can damage several components on the

terminal block. To avoid such 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-2636 terminal block

❑PXI chassis

❑NI PXI-2529 switch module

❑1/8 in. flathead screwdriver

3. Connect Signals

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

while referring to Figure 1.

1. Remove the terminal block top cover screw 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. Pull the signal wires through the strain-relief opening shown in

Figure 1.

5. Connect the safety earth ground to the safety ground lug.

6. Connect the wires to the terminals by inserting the stripped end of the

wire into the terminal. Secure the wire by tightening the screw for each

terminal. No bare wire should extend past the screw terminal. Exposed

wire increases the risk of a short-circuit and can result in a failure.

7. Remove the slack in the terminal block wiring by pulling the wires

through the strain-relief bar.

8. Tighten the two screws on the strain-relief bar until the signal wires are

secured.

9. Replace the terminal block top cover.

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