National Instruments SCXI-1301

The National Instruments SCXI-1301 Screw Terminal Block, designated by part number 777687-01, is an essential accessory for enhancing connectivity in SCXI systems. This terminal block features 20 screw terminals, including eight pairs designed for interfacing with the eight differential inputs of the SCXI-1140 module. Additionally, it offers dedicated terminals for connecting ground signals, such as AGND and a functional chassis ground, as well as a terminal for the HOLD signal. The SCXI-1301 can be mounted securely to the front of the SCXI-1181 and SCXI-1181K modules, providing flexibility in system design. Its shielded construction facilitates simple and reliable signal connections. Users can easily follow the labeled connections, as detailed in the user manual, ensuring proper wiring for optimal performance. To connect the SCXI-1301 to an SCXI module, users should align and fasten the terminal block to the module's front connector, securing it with the thumbscrews located on the rear. Required tools for installation include a wire cutter, insulation stripper, long-nose pliers, a flathead screwdriver, and Philips-head screwdrivers. It is essential to avoid exposing uninsulated wires beyond the screw terminals to mitigate the risk of short circuits. Although the SCXI-1301 has been designated as obsolete by National Instruments, it remains available for purchase and repair through Apex Waves.
