Description
The TBX-68T is a rack mountable terminal block that is designed with a built-in cold junction sensor. This terminal block is identified by part numbers 183364C-01 and 777232-01, placing it within the SCXI & Legacy category. It is specifically compatible with NI-435x products, including USB-4350, PCMCIA-4350, PXI-4351, and PCI-4351. The TBX-68T is characterized by its functionality as an isothermal terminal block.
For mounting, it is designed to be DIN-rail mountable, providing ease of installation in various settings. The connection type features a shielded board with screw terminals and 26-pin latched connectors, ensuring secure and reliable connections. Notably, it reserves channels CH0 for the cold-junction sensor and CH1 for auto-zeroing circuitry, enhancing its precision and functionality.
When it comes to signal conditioning accessories, the TBX-68T is compatible with the SC-2060 Series, ER-8, and SSR-8. It supports a wide range of signals including voltage signals, thermocouples, thermistors, and RTDs, making it versatile for various applications. For connectivity with compatible devices, it uses cables such as PSH32-30F (for PCMCIA-4350) and SH6868 & R6868 (for USB-4350, PXI-4351, PCI-4351).
It is important to note that the TBX-68T has been announced as obsolete by National Instruments but remains available for purchase and repairs by. This ensures that users of this terminal block can continue to receive support and maintain their systems effectively.
