3 SMB Connectors (Analog Signals)
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
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 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.
NI TB-2709 Installation Guide 2 ni.com
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.
Yo u 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 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.

Installation

The TB-2709 connects directly to the front panel of the PXI DAQ device, as shown in Figure 2.

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
module I/O connector.
3. Tighten the two terminal block mounting screws.

Signal Descriptions

Measuring Floating Signals

You can use the TB-2709 to measure floating and ground-referenced analog input signals. To measure floating signal sources, move the switch located under the rubber-sealed door on the enclosure cover for the AI channel you are using to the ON (floating source) switch position. In the floating source switch position, the amplifier negative terminal connects to ground through a 5 kΩ resistor in parallel with a 0.1 shows the TB-2709 switch configuration options.

Measuring Ground-Referenced Signals

It is possible to set the switch on the TB-2709 to either the floating or ground-referenced source position to measure ground-referenced signals. However, for best results, use the OFF (ground-referenced source) switch position to avoid ground loops. Refer to the S Series User Manual for more information on measuring floating and ground-referenced signals.

Cabling Options

This section describes the cabling options for accessing digital signals on the TB-2709.
A 14-pin connector on the bottom of the TB-2709 provides access to digital I/O signals. Use the MFIT-Pigtail Cable Assembly (part number 194123-01) to access digital signals on the TB-2709. The MFIT-Pigtail Cable Assembly features a 14-pin I/O connector on one end and pigtail
