INSTALLATION GUIDE
NI TB-2709
PXI Terminal Block for S Series Devices
This installation guide describes how to install and connect signals to the
NI TB-2709 terminal block for use with PXI-6123/6133 S Series devices.
The TB-2709 can also be used with the PXI-6122/6132 devices to access
the first four AI channels.
Introduction
The TB-2709 is a terminal block assembly consisting of nine SMB
connectors and a 14-pin I/O connector. The terminal block assembly
connects directly to the front panel

The nine SMB connectors on the TB-2709 allow you to easily connect analog input signals to your National Instruments device. The 14-pin I/O connector located on the bottom of the TB-2709 allows access to digital signals. Caution The TB-2709 is not designed for input voltages greater than 42 V /60 VDC, pk 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 /60 VDC can damage the TB-2709, any pk device c

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-2709 can come in contact. Connections, including power signals to ground and vice versa, that exceed any of the maximum signal

To connect the terminal block to the PXI module I/O connector, refer to Figure 2 as you complete the following steps: 1. Install the PXI module into the chassis and tighten the two module screws. You must install the PXI device before connecting the TB-2709. Refer to the DAQ Getting Started Guide for instructions on installing your PXI device. 2. Guide the terminal block onto the PXI module connector. Caution Do not force the terminal block when inserting it into or removing it from the PXI
