INSTALLATION GUIDE TB-2705 PXI™ TERMINAL BLOCK FOR E SERIES AND WAVEFORM GENERATION DEVICES This installation guide describes how to install and connect signals to the TB-2705 terminal block for use with PXI E Series and waveform generation devices. Introduction The TB-2705 is a terminal block assembly consisting of a printed circuit board, 62 screw terminals, and a plastic enclosure with a strain relief. The terminal block assembly connects directly to the front panel of National Instruments E Series and waveform generation devices, eliminating the need for an external cable. The TB-2705 allows you to easily connect analog input, analog output, counter-timer, and digital I/O signals to your National Instruments device. The 62 screw terminals allow access to every pin on the device with the exception of some digital ground signals that are common to one another. The TB-2705 also has a shielded strain-relief to secure your I/O wires and provide an adequate chassis-ground connection.

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. TB-2705 PXI Terminal Block 2 ni.com 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. 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-2705 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.

Installing the Terminal Block Refer to Figure 5 as you perform the following steps to connect the terminal block to the PXI module I/O connector. The connectors of both the PXI module and the terminal block are polarized. You can attach them in only one way. Do not force the terminal block when inserting it into or removing it from the PXI module I/O connector. Caution 1. Install the PXI module into the chassis and tighten the two module screws. You must install the TB-2705 terminal block on the PXI module after the module is installed in the chassis. 2. Guide the terminal block onto the switch module connector. 3. Tighten the two terminal block mounting screws. © National Instruments Corporation 13 TB-2705 PXI Terminal Block 2 3 1 2 3 4 5 6 7 1 1 Terminal Block Mounting Screws 2 PXI Chassis 8 3 PXI Module Connector Figure 5. Connecting the TB-2705 to an E Series or Waveform Generation Device The TB-2705 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 can damage the TB-2705, any device connected to it, and the host computer. Overvoltage can also cause an electric shock hazard for the operator. National Instruments is not liable for damage or injury resulting from such misuse. Caution TB-2705 PXI Terminal Block 14 ni.com Specifications This section lists the specifications of the TB-2705.
