National Instruments 783869-01 Terminal Block 

National Instruments part number 783869-01 is an identifying part number for the TB-4302, a Terminal Block for use with PXIe-4302 and PXIe-4303 modules. The NI 783869-01 Terminal Block, designed for the NI PXIe-4302/4303 Data Acquisition Modules, features 32 channels and connects seamlessly with the host PXIe module. It facilitates connections of single or multiple channels without requiring an external power supply. The terminal block integrates with NI-MAX application software for simultaneous filtered terminal recognition. Weighing approximately 1 lb.

This terminal block offers a CJC accuracy of up to 1.5 °C and supports a maximum analog voltage of 10 V. Its 96-pin female DIN connector interfaces with an 82-pin female screw terminal, providing a straightforward solution for routing signals from external sensors or devices to the Data Acquisition Module without the need for calibration. 

The 783869-01 includes a temperature sensor specifically for cold-junction compensation, crucial for accurate thermocouple temperature measurements. This sensor ensures precise temperature readings of the terminal block, enhancing measurement accuracy across different environmental conditions. It's important to handle and calibrate the Terminal Block carefully to maintain optimal accuracy in temperature measurements. Avoid using the TB-4302/4302C for connecting signals or making measurements in Measurement Categories II, III, or IV.
