Overview

Official PN：778717-66

TB‑2666 is a dedicated front-mounted screw terminal block exclusively matched with NI PXI‑2566 / PXIe‑2566 16‑channel SPST relay switch modulesNI. It provides independent screw wiring terminals for all 16 relay signal paths, additionally reserves dedicated pins for trigger input and trigger output synchronization signals. Rated up to 150 V max signal voltage (Measurement Category I), with 800 V impulse voltage withstand capability, and delivers ultra-high 100 GΩ DC isolation when paired with PXIe-2566 for low-leakage precision signal switching. The screw terminal design supports direct bare wire wiring without extra adapters, simplifying bench test, semiconductor parametric measurement and multi-channel automated signal routing setups.

PCIe S‑Series

NI S‑Series (61xx family) multifunction DAQ features true simultaneous‑sampling architecture with dedicated ADC per channel . Mostly PCI / PXI form‑factor, few native PCIe variants. It delivers near‑zero phase delay across channels, ideal for transient waveform capture, vibration, acoustic and other timing‑critical measurement tasks. Supported by NI‑DAQmx driver and compatible with LabVIEW, TestStand. Accessories are not interchangeable with X‑Series

PXIe X‑Series

NI PXIe X‑Series are high‑performance multifunction DAQ modules on PXIe bus. Built with STC3 timing engine, they integrate analog input, analog output, bidirectional DIO and four 32‑bit counter‑timers. Leverage PXIe high‑speed backplane for hardware triggering, retriggerable measurements and multi‑module synchronization with VHDCI‑68 connector. Fully compatible with NI‑DAQmx driver, supporting LabVIEW, TestStand, Python, C/C++ and C#. Widely applied for data acquisition, automated ATE and hardware‑in‑the‑loop test systems

NI‑9213 C‑Series Module

NI‑9213 is a high‑density C‑Series thermocouple input module for CompactDAQ and CompactRIO systems. It offers 16‑channel, 24‑bit thermocouple measurement with up to 75 S/s per‑channel sampling rate. Integrated cold‑junction compensation, open‑thermocouple detection and anti‑aliasing filters. 250 Vrms channel‑to‑earth isolation with NIST‑traceable calibration, spring‑terminal connector supporting all standard thermocouple types. Mix‑and‑match with other C‑Series modules, widely used for multi‑channel temperature monitoring, environmental chamber and thermal‑cycle testing

PXIe‑1065 chassis

PXIe‑1065 is NI high‑performance 18‑slot PXIe chassis, supporting mixed PXI and PXIe modules. It features 9 PXI slots, 4 hybrid slots, 3 PXIe peripheral slots and one PXIe system timing slotNI. High‑bandwidth backplane delivers low‑jitter 10 MHz /100 MHz reference clocks, supporting PXIe star trigger and multi‑module synchronization. Field‑replaceable modular power supply shuttle, temperature‑controlled variable‑speed fans, up to 30 W per‑slot cooling and rack‑mount capability. Widely deployed for multi‑channel ATE systems, hardware‑in‑the‑loop, signal acquisition and simulation test benches
