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 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 Vpk/60 VDC, even if you install a voltage divider that reduces the voltage to within the input range of the DAQ device.
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.
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.
